A rare case of cerebral proliferative angiopathy with acute cerebral infarction and facial capillary malformation

We are describing a case of a 14-year-old girl who developed acute cerebral infarction which was documented on diffusion-weighted magnetic resonance imaging (DWI). On detailed evaluation, diagnosis of cerebral proliferative angiopathy (CPA) was made. Incidentally, she had capillary malformation on the forehead contralateral to cerebral vascular malformation. To our knowledge, this is the first case of CPA in the literature where DWI abnormality was due to acute cerebral infarction.

Role of endovascular embolization for trigeminal neuralgia related to cerebral vascular malformation

Objective The objective of this article is to describe the trigeminal neuralgia related to cerebral vascular malformation that is rarely reported and the experience referring to endovascular treatment. Patients and methods A total of 10 patients who had cerebral vascular malformation (AVM and dAVF) in a single center presented with trigeminal neuralgia. Clinical and angiographic presentations as well as their clinical outcomes after embolization were reviewed. Results Of the 10 cases, seven dAVFs and three AVMs were detected. In contrast to the dilated feeding arteries, an ectasia of the draining vein that is adjacent to the root entry zone of the trigeminal nerve such as the petrosal vein and lateral mesencephalic vein has the major role in causing the trigeminal neuralgia. All of these patients had relief of facial pain after endovascular embolization during follow-up (mean 57.3 months, range 5 to 100 months). There were no permanent neurological deficits. Conclusions Endovascular embolization is an effective method in treating trigeminal neuralgia related to cerebral vascular malformation.

Vein of Galen malformation, a rare cause of epilepsy

Vein of Galen malformation (VOGM) is a rare congenital cerebral vascular malformation characterized by an aneurysmally dilated midline deep venous structure, fed by abnormal arteriovenous communication. Most patients develop severe congestive heart failure at neonatal period that is fatal if left untreated. Rarely, patients with low-flow fistula present with headache, seizure, or focal neurological sign at adulthood. A 28-year-old female with VOGM-related epilepsy was introduced in this brief report.

Pseudoephedrine-induced Hemorrhage Associated with a Cerebral Vascular Malformation

ABSTRACT:Background:Sympathomimetic-related intracerebral hemorrhage is well-documented. Most cases are associated with phenylpropanolamine use.Case Report:We report a case of intracerebral hemorrhage occurring in a middle-aged man who suffered from chronic sinusitis and had been ingesting pseudoephedrine daily for one year. This patient was previously well with no known cardiovascular risk factors. Clinical examination revealed no evidence of vasculitis nor coagulopathy and initial neuroimaging (i.e., computed tomography, angiography, magnetic resonance imaging) demonstrated no features consistent with aneurysm, arteriovenous malformation (AVM), cavernoma, nor cerebral metastases. A follow-up cerebral angiogram demonstrated a small AVM arising off a branch of the pericallosal artery and a small arteriovenous fistula arising off the costal marginal branch. The AVM was embolized without incident, however, the AVF was not accessible.Conclusions:Sympathomimetics have long been associated with intracerebral hemorrhage. Since 1979, over 30 published case reports have documented the relationship between phenylpropanolamine and stroke. Only one report links phenylpropanolamine consumption to an intracerebral hemorrhage in a patient with an AVM. There is a paucity of literature etiologically inculpating other ephedra alkaloids in the causation of intracerebral hemorrhage. This is a case of pseudoephedrine-induced intracerebral hemorrhage in a patient with an underlying vascular malformation.
