Cerebral Venous Infarction Due to Brachial Artery-Jugular Vein Jump Graft in a Hemodialysis Patient

Hemodialysis patients rarely experience neurologic symptoms related to their vascular accesses. However, occlusion of venous drainage induces extreme venous hypertension and in rare cases cause intracranial venous congestion. We report a patient with cerebral venous infarction resulting from reflux flow into the cranium induced by an arteriovenous jump graft to the internal jugular vein. Clinicians should take into account the possibility of neurologic deficit related to intracranial venous hypertension in hemodialysis patients.

Multimodal Imaging Follow-up of a Thrombosed Developmental Venous Anomaly: CT, CT Angiography and Digital Subtraction Angiography / 신경중재치료의학

We report a rare case of thrombosed developmental venous anomaly (DVA) in a 31-year old male with hemorrhagic cerebral venous infarction at the initial clinical presentation. In this case, sequential CT, CT angiography and digital subtraction angiography demonstrated thrombotic obstruction of the venous drainage from DVA, its progressive recanalization and temporal evolution of the affected brain parenchyma. The relevant previous literatures were reviewed and summarized.

Cerebral Venous Angioma Complicated by Non-hemorrhagic Venous Infarction

Venous angioma is normally asymptomatic, but it can present with clinical presentations such as seizures, headache, and focal neurological deficits. Brain hemorrhage is known to be the most common complication, with nonhemorrhagic brain infarction due to venous angioma being very rare. We report the first case of supratentorial venous angioma complicated by nonhemorrhagic venous infarction. This case occurred in a 49-year-old female, and was confirmed by magnetic resonance (MR) imaging including contrast-enhanced MR venography and perfusion imaging.

Meningioma en Plaque of Parasagittal Region Presented with Recurrent Venous Infarction

A case of parasagittal meningioma en plaque with a peculiar clinical presentation is reported with a review of the literature. A 72-year-old woman presented with dysphasia and right hemiparesis. Computed tomography and magnetic resonance imaging demonstrated focal edema of left frontal lobe and a thick sheet-like parasagittal enhancing lesion with extension along the falx cerebri and adjacent sulcal enhancement. Differential diagnosis included idiopathic hypertrophic pachymeningitis, meningeal neurosarcoidosis, metastasis and meningioma en plaque. Cerebral angiography revealed occlusion of the anterior one-third of the superior sagittal sinus as well as a faint tumor blush supplied from the anterior branch of the middle meningeal artery. At surgery, the tumor invading the dura and skull was removed totally but the tumor invaded into the superior sagittal sinus was removed subtotally. The tumor was confirmed to be a transitional meningioma on pathological examination.
