RESUMEN

The occurrence of arterial and venous thrombosis during coronavirus infection has been widely reported since the beginning of the epidemic. Floating carotid thrombus (FCT) in the common carotid artery is exceptional and its main known cause is atherosclerosis. We describe the case of a 54-year-old man who developed, one week after the onset symptomatology of related to COVID-19 infection, an ischemic stroke, complicating a large intraluminal floating thrombus in the left common carotid artery. Despite surgery and anticoagulation, a local recurrence with other thrombotic complications occurred and the patient died.

RESUMEN

Spinal dural arteriovenous fistulas (SDAVFs) are rare entities and are often misdiagnosed. They usually occur in adults above the age of 50 and 60 years. While they most commonly involve the thoracolumbar region, they can occur anywhere along the spinal cord. Clinical symptoms are insidious and not specific and may progress slowly, over several years, to severe myelopathy with paraplegia. Early diagnosis is critical because the deficits are potentially reversible if carefully treated. Delayed treatment may result in severe and irreversible neurological disability. Imaging diagnosis relies on MRI and conventional spinal angiography. Once identified, the dural arteriovenous fistula should be immediately treated by either endovascular embolization or surgical ligation. In this report, we present a case of SDAVF in a 65-year-old male that was managed by open surgery.

RESUMEN

INTRODUCTION: Epiploic appendagitis is a torsion of fatty appendages of ligamentum trees (1), it's a rare cause of abdominal pain that usually manifests by right or left iliac fossa pain, reminding of appendicitis, diverticulitis or ischemia of the omentum. CASE PRESENTATION: We report the case of a 56 years old male patient admitted for an epigastric pain and a right-upper quadrant abdominal pain, for whom he underwent an abdominal ultrasound and a CT-scan who shown an abscessed mass under colic transverse to the unusual seat. DISCUSSION: CT scan is still the key modality for diagnosis, avoiding unnecessary surgery. Complications of primary epiploic appendagitis have rarely been described in the literature (Hwang et al., 2013; Hasbahceci et al., 2012). Another more rare complication is appendagitis with associated abscess, in this condition, we must also think about complicated diverticulitis. The treatment of uncomplicated forms is generally conservative, however, some authors have suggested a surgical method (Saad et al., 2014). For therapeutic management of its complication, there has been much interest in the use of minimally invasive techniques such as percutaneous drainage to minimize the morbidity and mortality that is associated with surgery (Evidence National Guideline Centre (UK), 2019). CONCLUSION: The diagnosis of epiploic appendagitis is still uncommon, CT scan can eliminate other diagnosis of acute abdominal pain such as diverticulitis and appendicitis. It also allows the diagnosis of the rare complicated forms such as abscesses associated with epiploic appendagitis. The treatment of typical forms is usually conservative, while the complicated form requires surgery because of the potential associated pathology.

RESUMEN

Jejunal pseudoaneurysm is a rare complication of pancreatitis, usually manifested by digestive bleeding when it ruptures into the digestive lumen. This complication is extremely rare and may be life-threatening. The diagnosis is based on abdominal angiographic computed tomography. Radiology allows therapeutic management through arterial embolization. This case report describes a pseudoaneurysm of jejunal artery that developed as the result of pancreatitis: A 77-year-old man seen in early September 2015 at the emergency department for acute pancreatitis had a pseudocyst infected and spontaneously fistulized into the jejunum lumen. His condition responded initially to symptomatic therapy, and he was discharged. He returned two years later, with digestive bleeding from jejunal pseudoaneurysm that had ruptured into the jejunal lumen. Angiographic embolization was performed as first-line treatment with good outcome. Bleeding more than two years after acute pancreatitis due to rupture of a jejunal pseudoaneurysm is an exceptional complication. Here we report a rare case of digestive hemorrhage caused by jejunal pseudoaneurysm, complicating acute pancreatitis.

RESUMEN

We report here a case of aorto-cava fistula complicating the rupture of a sub-renal aortic aneurysm into the inferior vena cava, which is a rare complication of aortic abdominal aneurysms with often-fatal outcome. Abdominal computed tomography with multi-planar reconstructions remains the firstline-imaging tool allowing positive diagnosis and preoperative planning. Treatment may be surgical or endovascular.

RESUMEN

Pulmonary tuberculosis (TB) is a common worldwide infection and a medical and social problem causing high mortality and morbidity; especially in developing countries.In accordance with the virulence of the organism and the defenses of the host; tuberculosis can occur in the lungs and in extrapulmonary organs. A variety of sequelae and complications can occur in the pulmonary and extrapulmonary portions of the thorax in treated or untreated patients.In this article; we aimed to review the characteristic imaging findings of various sequelae of thoracic tuberculosis affecting the lung parenchyma; airways; vessels; mediastinum; pleura; and chest wall
