'Dense Inverted Triangle Sign' in Cerebral Venous Thrombosis
Intern Med. 2022 Nov 30. doi: 10.2169/internalmedicine.0764-22. Online ahead of print.ABSTRACTThe early diagnosis of cerebral venous thrombosis in the emergency department is challenging. A 70-year-old man presented to the emergency department after falling with new-onset convulsions. Brain unenhanced computed tomography (CT) revealed right frontal hemorrhage indicative of traumatic subarachnoid hemorrhage (SAH). Brain unenhanced CT on day 2 revealed increased density in the anterior superior sagittal sinus (SSS), namely 'dense inverted triangle sign.' Brain magnetic resonance venography showed a filling defect in the ante...

A Rare Case of Clival Metastasis in a Patient with Gastric Cancer.
We report a rare case of clival metastasis from gastric cancer. A 73-year-old man with advanced gastric cancer treated with nivolumab as a third-line chemotherapy experienced headache, tongue deviation, and difficulties in speaking clearly. We suspected stroke or brain metastasis, but brain contrast-enhanced magnetic resonance imaging demonstrated a clival mass, diagnosed as clival metastasis from gastric cancer. The tumor could not be identified by plain computed tomography and plain magnetic resonance imaging alone. He received palliative radiotherapy (30 Gy/10 fr); his symptoms improved gradually. Although metastasis fr...

Embolic Stroke Due to a Mural Thrombus in the Ascending Aorta Following Cisplatin-based Chemotherapy.
Authors: Ochiai Y, Tsunogae M, Ueda M Abstract A 59-year-old woman with small-cell lung carcinoma achieved tumor disappearance after cisplatin-based chemotherapy (CBC) and radiation treatment but subsequently experienced right hemiparesis and aphasia. Brain magnetic resonance imaging revealed a left middle cerebral artery territory acute infarction and left internal carotid artery occlusion. Ultrasonography revealed a mobile thrombus in the left common and internal carotid arteries, and contrast computed tomography revealed a mural thrombus in the ascending aorta. Based on these findings, embolic stroke due to aort...

Diagnostic Yield of Early Examination for Venous Thrombosis in Patients with Cryptogenic Stroke and a Right-to-left Shunt.
Conclusion CS patients, especially those with multi-territory lesions, should be immediately examined for DVT and PE. PMID: 32295996 [PubMed - in process]

Thrombolysis-related Multiple Lobar Hemorrhaging in Cerebral Amyloid Angiopathy with Extensive Strictly Lobar Cerebral Microbleeding.
Authors: Eriguchi M, Yakushiji Y, Tanaka J, Nishihara M, Hara H Abstract A hemi-paralyzed 86-year-old man was diagnosed with ischemic stroke and underwent thrombolysis. Pre-thrombolysis brain magnetic resonance imaging revealed extensive strictly lobar cerebral microbleeding (CMB). Post-thrombolytic computed tomography revealed asymptomatic multiple intracerebral hemorrhaging (ICH). His age, CMB topography, and decreased cerebral spinal fluid amyloid-β 40 and 42 levels were compatible with a diagnosis of cerebral amyloid angiopathy (CAA). There is no consensus on the safety of thrombolysis for acute stroke patient...

Functional Outcomes of Decompressive Craniectomy in Patients with Malignant Middle Cerebral Artery Infarction and Their Association with Preoperative Thalamus Deformation: An Analysis of 12 Patients.
Conclusion Patients with preoperative thalamus deformation caused by pressure and edema show a poor oral intake and communication abilities after DC, suggesting that preoperative thalamus deformation is a predictor of poor functional outcomes after DC in patients with malignant MCA infarction.
