Image en popcorn cérébrale

Abstract

Cerebral cavernous are vascular lesions defined by the presence of deformed capillaries without interposition of nervous tissue. These are relatively rare (0.1 to 0.5% of the general population and less than 5% are symptomatic), clinical symptomatology is dominated by hemorrhage and epilepsy, and also depends on the location. Cerebral MRI is the gold standard for diagnosis, therapeutic approach and following. We report the clinical case of 27 old man, with no history, who presented two generalized convulsive seizures a week ago. Clinical examination was normal. Brain MRI has objectified a left frontal lesion with typical appearance in popcorn and combining hyper signal (recent bleeding or calcifications) and hypo signal (hemosiderin deposition bleeding = old) on T2-weighted images. The patient was put under antiepileptic treatment (valproic acid) with total seizure control.
