RESUMEN
A 74-year-old man presented with persistent hiccups and headache persisting for 2 days. An anticoagulant was administered for his coronary heart disease. Cranial computed tomography (CT) revealed an intracerebral hemorrhage (ICH) located in the right occipital lobe, without any abnormal findings around the brainstem. The patient underwent endoscopic hematoma evacuation via a burr hole, resulting in immediate resolution of hiccups. Following an uneventful postoperative course, the patient experienced recurrent hiccups on the 47th day postsurgery. A subsequent CT scan taken on the 50th day revealed a compressive chronic subdural hematoma (CSDH) situated in the right frontoparietal convexity. The patient underwent burr-hole irrigation, leading to prompt cessation of the hiccups. Persistent hiccup should be recognized as potential manifestation of supratentorial lesions, including ICH or CSDH. Surgical evacuation of such lesions can rapidly alleviate hiccups associated with these pathologies.
RESUMEN
A 17-year-old boy presented with a high-grade fever. The patient had been previously diagnosed with Cornelia de Lange syndrome (CdLS). The patient visited a local physician and was diagnosed with sinusitis. Owing to persistent fever, the patient was referred to our hospital. At the initial presentation, his body temperature was 38.2°C, while maintaining previous living activities and neurological function. Despite changing the antibiotic to amoxicillin, the patient's fever persisted with worsened activity. At the second presentation, the patient presented with left hemiparesis. Blood examination revealed increased white blood cell count and serum C-reactive protein level. Emergency magnetic resonance imaging revealed acute cerebral infarcts in the right cerebral hemisphere, with evident stenosis in the right paraclinoid segment of the internal carotid artery (ICA). In addition, an abscess was found in the cerebellar hemisphere, which was punctured through the burr hole. Computed tomography performed after the completion of antibiotic therapy revealed a restored diameter of the stenotic ICA. Sinusitis can cause ischemic stroke due to compressive stenosis of the paraclinoid ICA, particularly in patients with CdLS. Sinusitis should be preferentially managed in patients with CdLS.
RESUMEN
A 50-year-old man presented with headache and left hemiparesis. No noticeable preceding head trauma was observed. Computed tomography (CT) scans revealed a compressive chronic subdural hematoma (CSDH). The patient underwent burr-hole irrigation, during which he was considerably restless. In addition, extensive avulsion was found in the parietal dura mater posterior to the burr hole. CT performed immediately after the surgery revealed the emergence of a thick epidural hematoma (EDH) located posterior to the burr-hole. During emergency craniotomy for the EDH, there was no identifiable injury to the dura mater or the meningeal vessels. However, a review of the CT scans confirmed well-developed diploic spaces just above the center of the EDH, with connecting channels between the diploic spaces and extracranial sites. Based on these observations, we assumed that the diploic vein might have caused the EDH. Diploic veins can cause AEDH after burr hole irrigation for CSDH. Appropriate intraoperative sedation and protective irrigation maneuvers can reduce the risk of such AEDH.
RESUMEN
A 43-year-old, previously healthy man experienced a decreased sensation in the left lower extremity without preceding spinal trauma. At presentation, the patient exhibited slight motor weakness in the left lower extremity, in addition to decreased pain sensation below the ipsilateral T7. Spinal magnetic resonance imaging (MRI) revealed abnormal findings consistent with idiopathic thoracic spinal cord herniation (ITSCH) at the T5/6 level. Computed tomography (CT) revealed a small vertebral erosion at the lower T5. The patient's symptoms gradually progressed over the next 3 years. MRI revealed marked lateral elongation of the cord at the T5/6 and apparent intravertebral cord herniation. The patient underwent ITSCH reduction through T5-6 laminectomies. The herniated cord was vertically long with a bulbous rostral part. Successful ITSCH reduction was achieved and the patient's postoperative course was uneventful. ITSCH is a progressive pathology that requires prompt surgical reduction. Certain ITSCHs may be complicated by intravertebral cord herniation.
RESUMEN
A 53-year-old woman presented with a 2-week history of headache and vertigo. Computed tomography revealed a hyperdense tumor, measuring 30 × 31 × 36 mm in diameter, in the anteromedial parts of the cerebellar hemispheres. Cerebral magnetic resonance imaging 10 days later revealed an apparent extra-axial tumor with broad attachment to the medial tentorium cerebelli and rapid growth to a diameter of 40 × 41 × 46 mm. Cerebral angiography revealed no obvious feeding vessels or tumor stains. The patient underwent biopsy through the left occipital transtentorial route. The histological appearance was consistent with diffuse large B-cell lymphoma. Intracranial lymphoma may present as a dural tumor that mimics a meningioma. Rapid tumor growth incongruous with benign meningiomas should be assumed to be possible lymphoma, and prompt biopsy should be performed.
RESUMEN
A 53-year-old woman was brought to the emergency room with headache and progressive deterioration of consciousness. Radiological examinations revealed acute subdural hematoma extending along the cerebellar tentorium to the falx cerebri, and a mass lesion with hemorrhage in the left cerebellum, with acute hydrocephalus. Emergency tumor and hematoma removal with decompressive craniectomy of the occiput was performed. Histopathological diagnosis was microcystic meningioma. Postoperatively, the patient recovered to clear consciousness with sequelae of left cerebellar ataxia, cerebellar dysarthria, and vertigo. This case of tentorial microcystic meningioma associated with acute subdural hematoma in the posterior cranial fossa is extremely rare, with only reported 4 similar cases.
