RESUMEN

Background: Hemoptysis is defined as coughing out of blood. Pulmonary tuberculosis is the most common cause of hemoptysis in tuberculosis-endemic countries like India. Rasmussen aneurysm is a pseudoaneurysm arising from the pulmonary artery adjacent to or within a tuberculous cavity. Chest radiographs, chest computed tomography angiography (CTA), and digital subtraction angiography (DSA) are the imaging tools for evaluating a case of hemoptysis. Case: A 32-year-old man with a history of pulmonary tuberculosis presented with complaints of recurrent hemoptysis. On imaging evaluation, multiple pulmonary artery pseudoaneurysms were seen in the left lung. The patient was shifted to the DSA lab and the pseudoaneurysms were subsequently treated by endovascular coil embolization. Hemoptysis resolved following the procedure and the patient was again started on anti-tubercular therapy. Conclusion: Endovascular coiling is minimally invasive, safe, and effective management of multiple Rasmussen aneurysms for preventing possible torrential blood loss and unfortunate death.

RESUMEN

Rasmussen aneurysm refers specifically to a pseudoaneursysmal dilatation of a branch of the pulmonary artery adjacent or within a tuberculous cavity. The incidence of pulmonary vascular complication secondary to tuberculosis is very rare hence underdiagnosed by many clinicians. It can present with life threatening haemoptysis and CT angiography plays an important role in localizing the lesion and guiding treatment. On contrary the most common cause of massive haemoptysis is of bronchial artery origin. Early diagnosis and proper interventions are essential as it is associated with high mortality. Herein we report three cases of Rasmussen aneurysm in patients with haemoptysis. Only one patient underwent emergency trans-arterial embolization of the involved pulmonary artery.

RESUMEN

Rasmussen aneurysm (RA) is an uncommon cause of hemoptysis in pulmonary tuberculosis, first described in 1868 by Rasmussen. It is often treated with surgery or endovascular coiling. A few cases of spontaneous resolution with conservative management have been recorded in literature. We present the case of a 44-year old patient who reported with hemoptysis, weight loss, chronic cough and night sweats and was diagnosed of pulmonary tuberculosis on the basis of clinical assessment and chest X-ray. Subsequently, chest CT scan done showed a giant left RA, treated conservatively with antituberculous chemotherapy with complete radiological resolution of aneurysm after 18-month follow-up. We conclude that conservative management of RA is a good alternative in a low resource setting for hemodynamically stable patients.

RESUMEN

Hemoptysis involves compromised pulmonary vasculature of bronchial versus pulmonary arterial origins, with both life-threatening and non-life-threatening causes. Life-threatening hemoptysis is uncommon. To date, published cases of Rasmussen aneurysm remain low and subsequently underrecognized. We report on a 63-year-old male from Mexico with a more than 30-pack-year smoking history, but no history of lung disease, who presented to the emergency department with cough and hemoptysis for one week. A computed tomography angiography (CTA) chest demonstrated a pseudoaneurysm and hemorrhage, consistent with a Rasmussen aneurysm. Interventional radiology performed a pulmonary angiography, and subsequent coil embolization of the tertiary feeding arteries was performed. This case demonstrates a rare pulmonary artery pseudoaneurysm, known simply as Rasmussen aneurysm, that was successfully managed with coil embolization and highlights the importance of considering the disease in the differential diagnosis for patients with hemoptysis.

RESUMEN

Rasmussen's aneurysm was originally described as a rare cause of hemoptysis in tuberculosis. Dilatation of the pulmonary artery wall is caused by tuberculosis inflammation. Recently, the incidence of non-tuberculous mycobacterial (NTM) disease has increased; it now exceeds that of tuberculosis. We report a Rasmussen's aneurysm due to NTM.

RESUMEN

Massive hemoptysis due to pulmonary tuberculosis is a life-threatening complication; it occurs as a result of the erosion of one of the pulmonary vessels. Tuberculous vascular lesions can also lead to arteritis, thrombosis, arterial dilation and Rasmussen aneurysms. "Rasmussen aneurysm" is a rare cause of hemoptysis. The extent of hemoptysis varies in severity from mild to life threatening, which is more common. Here, we report a case of a 45-year-old Indian male who initially presented with cough, and generalized weakness; his clinical, laboratory, and radiological findings were highly suggestive of pulmonary tuberculosis. Following medical ward admission, two weeks later he had worsening of his respiratory status complicated by massive hemoptysis and dropped oxygen saturation requiring intubation and admission to the intensive care unit. His computed tomography angiography revealed localized aneurysmal dilatation of the pulmonary artery in the left lower lobe (Rasmussen aneurysm); embolization was performed successfully. Due to the poor respiratory reservoir in most pulmonary TB cases, interventional radiology is preferred over surgery.

RESUMEN

Rasmussen's aneurysm is a rare and life-threatening cause of recurrent hemoptysis in post tuberculosis patients. Appropriate and early treatment can prevent complications like severe life-threatening hemoptysis due to aneurysm rupture.

RESUMEN

Rasmussen's aneurysm is a pseudoaneurysm caused by tuberculosis, when cavitation occurs adjacent to a pulmonary artery, which can be lethal. It is a rare complication usually affecting adults. This is a case of an 9-year-old boy initially admitted for pneumonia that developed hemoptysis during admission. Chest X-ray done after this episode showed development of a left hilar mass not present in the previous studies. A chest CT with contrast subsequently revealed a saccular aneurysm arising from the left lower lobe pulmonary artery adjacent to a cavity, a Rasmussen's aneurysm. The patient was treated conservatively with continuation of anti-TB medication and serial monitoring due to the size of the aneurysm being less than 6 cm and spontaneous resolution of the hemoptysis. This report stresses that a Rasmussen's aneurysm should always be in the differential diagnosis of a hilar mass in a patient with hemoptysis, regardless of the patient's age.

RESUMEN

Rasmussen's aneurysm is a very uncommon condition occurring in post-pulmonary tuberculosis patients. We are presenting a case of a young male patient with the chief complaints of hemoptysis, breathlessness on exertion, cough with expectoration and fever, and weight loss. A thorough radiological examination revealed multiple cavitary lesions, bronchiectasis, tree-in-bud appearance and pulmonary nodules, and areas of air-spaced opacities, indicating a likely diagnosis of post-primary pulmonary tuberculosis with stages of active infection and healed infection. The post-contrast study revealed a well-defined dilated vascular channel arising from a branch of the right pulmonary artery indicating pseudo-aneurysm formation, i.e., Rasmussen's aneurysm, within a large cavity in the right middle lobe. The patient underwent emergency trans-arterial embolization successfully and he was stable postoperatively.

RESUMEN

Pulmonary tuberculosis is widely prevalent, and the survivors of this disease often present to healthcare facilities with long-term sequelae of the disease. Presented here is a case of a 25-year-old male who presented with concerns of fever, cough with expectoration, and blood in sputum. The patient was managed as per protocol in suspicion of necrotizing pneumonia and re-activation of tuberculosis (TB) as suggested by investigations. The hemoptysis gradually increased over time. With suspicion of a vascular aneurysm and in view of increasing hemoptysis, an early high-resolution computed tomography (HRCT) scan of the chest and a computed tomography (CT) scan of the bronchial angiography were performed. A diagnosis of Rasmussen's aneurysm was made radiologically, and this rare and under-reported sequelae of TB in contemporary times was brought into notice. A holistic and multi-disciplinary approach involving emergency medicine physicians, internists, anesthesiologists, critical care physicians, pulmonologists, and radiologists can ensure optimal outcomes for such cases in hospital setups if timely intervened.

RESUMEN

Rasmussen aneurysm is rare diagnosis occurring in patients with long-standing tuberculosis. TB-COVID-19 co-infection in the context of Rasmussen aneurysm is a rare occurrence, yet new cases are emerging. An elderly male was recently diagnosed with TB-COVID-19 co-infection and presented with sudden onset massive hemoptysis. The patient was diagnosed with Rasmussen aneurysm after being evaluated by computed tomography pulmonary angiogram due to a suggestive clinical presentation. Interventional radiologists planned for embolization of pulmonary artery, with an unidentifiable source. It was suspected that the patient's source of bleeding was hampered due to local tamponade effect or thrombosis of the aneurysm. The patient remained stable after 24 hours on computed tomography pulmonary angiogram. Our case emphasizes the importance of Rasmussen aneurysm as a differential diagnosis when presented with a TB-COVID-19 co-infection and sudden onset of hemoptysis symptomatically and radiologically. The timely diagnosis and management are key to improve mortality.

RESUMEN

PURPOSE: Pulmonary tuberculosis (PTB) has clinically significant sequelae, even after recommended treatment completion. It is important to recognise these sequelae for accurate assessment of severity and treatment planning, if indicated. MATERIAL AND METHODS: We retrospectively analysed contrast-enhanced computed tomography (CT) scans of chest of 100 patients with previous history of treated pulmonary tuberculosis, excluding those with active pulmonary disease. CT findings were analysed based on parenchymal, airway, pleural, mediastinal, and vascular sequelae of PTB. RESULTS: Parenchymal sequelae included fibrosis with architectural distortion and volume loss (90%), cavities (21%) (with aspergillomas noted in 19% of these cases), and tuberculomas (54%). Airway involvement was noted as bronchiectasis (77%) and bronchial stenosis (4%) but none with broncholithiasis. Mediastinal sequelae included lymph node calcification (74%), fibrosing mediastinitis (1%), and pericardial tuberculosis (2%). Pleural sequelae included pleural thickening (22%), with 40.9% of these patients showing calcifications, and one patient with chronic chylous pleural effusion. Vascular sequelae included Rasmussen aneurysms (4%), enlarged bronchial arteries (3%), and systemic bronchial collaterals in 1% of our patients. CONCLUSIONS: PTB has multiple appalling sequelae, which require due attention and appropriate treatment in symptomatic cases. Radiological evaluation forms an integral part in patient assessment and decision making.

RESUMEN

Examine computed tomography angiography before performing transbronchial biopsy in patients with haemoptysis.

RESUMEN

Rasmussen's aneurysm (RA) is a pseudoaneurysm of a pulmonary artery (AP), adjacent to or within a tuberculous cavity, appearing in 5% of these lesions. Its rupture might provoke massive hemoptysis (MH) with a near 50% mortality. The aim of this article is to report a case of massive hemoptysis following Rasmussen's aneurysm. 52-year-old man with recent history of hospita-lization due to pneumonia associated to influenza A and decompensated hyperthyroidism, pre-sents outpatient chest radiograph with signs of hyperinflation and scarring apical opacities, the patient returned to the hospital due to sharp pain of left hemi thorax during inspiration accom-panied with bloody sputum, asthenia and non-quantified weight loss. He evolves to frank MH, requiring endotracheal intubation managed in the intensive care unit (ICU). Chest computed tomography (CT) reported ground-glass opacity, nodules with a tendency to cavitation, tree-in-bud pattern in agreement with inflammation and infection, active TB is considered, and truncus of PA with vascular lesion suggestive of aneurysm dependent on pulmonary circulation, possibly RA. Fibrobronchoscopy reported signs of old and recent bleeding of left bronchial tree, probably of the lingula, blood clots in right bronchial tree. Molecular study and TB cultures was negative. Endovascular procedure with arteriography was carried out, revealing amputation of left distal segmental PA carrying the pseudoaneurysm with complete regression, discarding embolization RA It must be considered among the differential diagnoses of MH, especially on patients with pulmonary TB complications, such as the reported case. Due to its associated increased morta-lity, once RA is identified, it must be either endovascularly or surgically eradicated.

RESUMEN

The authors report multiple giant bilateral pseudoaneurysms of pulmonary artery, also known as Rasmussen's aneurysms, which remained silent and unrevealed despite the large size and multiplicity unearthed by fluorine-18 fluorodeoxyglucose positron emission tomography/computerized tomography.

RESUMEN

Rasmussen's aneurysm, a very rare complication of active pulmonary tuberculosis (TB), is a pulmonary artery aneurysm adjacent to or within a tuberculous cavity. It may lead to rupture and life threatening massive hemoptysis, an uncommon but challenging medico-surgical emergency. This complication warrants attention in view of the resurgence of tuberculosis and increasing occurrence of multi-drug resistant TB, especially in resource-poor, high-TB burden countries like India. We present a case of an elderly man who presented to the emergency room with low-grade fever, cough and hemoptysis. Thoracic Multidetector row Computed Tomographic Angiography (MDCTA) showed left upper lobe consolidation with thick walled cavitary lesions and aneurysm along the apical segmental branch of left upper lobar pulmonary artery. Hemoptysis was successfully controlled with systemic artery embolization using polyvinyl alcohol (PVA) particles. He was treated with antitubercular chemotherapy and was followed for more than a year without further recurrence of hemoptysis.

RESUMEN

A 77-year-old man with a progressively dry cough (two months duration) was admitted with hemoptysis. Chest computed tomography (CT) revealed left lingular lobe consolidation and one thick-walled cavity lesion over the left lower lobe, which was accompanied by satellite micro-nodules in a tree-in-bud pattern. CT-guided biopsy confirmed mycobacterial infection, and subsequent culture yielded Mycobacterium avium complex (MAC). Unremitting hemoptysis was present despite treatment (14 days) with ethambutol, rifampin, clarithromycin, and streptomycin. Initial CT angiography (CTA) to determine the source of the hemoptysis revealed a suspected aneurysm in the consolidated left lingular lobe; however, this could not be localized via catheter angiography during the pulmonary and bronchial arterial phases. Two weeks later, a massive hemoptysis episode led to haemodynamic instability and serious consequences. Follow-up CTA confirmed the previously detected aneurysm, and glue embolization was performed successfully. This case report highlights a rare but catastrophic MAC-associated pseudoaneurysm and relevant treatment options.

RESUMEN

The authors report an extremely rare occurrence of a massive aneurysm of a major pulmonary artery branch vessel caused by adjacent necrotizing aggressive squamous cell carcinoma metastatic mediastinal nodes. Despite the huge size, there was no hemoptysis due to the walling off effect by the necrotic nodes.

RESUMEN

Rasmussen's aneurysm is an inflammatory pseudo-aneurysmal dilatation of a branch of pulmonary artery adjacent to a tuberculous cavity. Life threatening massive hemoptysis from the rupture of a Rasmussen's aneurysm is an uncommon yet life threatening complication of cavitary tuberculosis (TB). We present a case of a young woman who presented with low-grade fever and hemoptysis. Computed tomographic (CT) angiography showed biapical cavitary lesions and actively bleeding aneurysms involving pulmonary artery, which successfully underwent glue embolization.

RESUMEN

Hemoptysis as a sequelae of past tubercular infection of lungs is a known occurrence. Hemoptysis in such a patient can result from a number of etiologies like tubercular reactivation, bronchiectasis, aspergiloma and vascular complications like hypervascularity from bronchial arteries, arteriovenous fistula formation, pseudoaneurysms, etc. Massive hemoptysis in such a patient is usually treated by bronchial artery embolization and occasionally by surgical lobectomy. A rare source of bleeding in such a patient is from Rasmussen's aneurysm arising from the pulmonary arteries. We report a young patient of treated pulmonary tuberculosis who had recurrent hemoptysis. He was treated earlier with bronchial artery embolization. On recurrence of hemoptysis, he was reevaluated and was found to have multiple Rasmussen's aneurysms arising from the pulmonary arteries, which were successfully treated by coil embolization.
