Presentation
Left-sided hemiparesis
Patient Data
Intraparenchymal hemosiderin stained popcorn like lesion with surrounding edema is seen paramedian right fronto-parietal lobe and posterior part of body of corpus callosum . Lesion shows mixed signal intensity on both T1 and T2Wt sequences with hypointense T2 rim consistent with hemosiderin deposition. T2 GRE shows typical blooming artefact. TOF/3D angiogram do not demonstrate arterial venous malformation.
Case Discussion
Cerebral cavernous venous malformations are labeled as slow flow venous malformations having no arterial feeders. DSA is useful to differentiate a cerebral cavernous malformation from an arteriovenous malformation or developmental venous anomaly.
Most of the cases are asymptomatic but in this case patient presented with neurological deficit secondary to hemorrhage. As per Zabramski classification of cerebral cavernous malformations, this is type II which is most common type showing classic popcorn lesion.
