Presentation
Known case of epilepsy.
Patient Data
Three T2 centrally hyperintense lesions with thin T2 hypointense rim in the right high posterior parietal cortex, right dorsal hemipons and right cerebellar hemisphere showing blooming on gradient imaging. The larger lesions in right parietal lobe and pons show focal intralesional T1 hyperintense signal.
No perilesional gliosis or edema.
Case Discussion
The features in this case are consistent with multiple cerebral cavernomas.
Cerebral cavernoma is a vascular malformation seen in brain and spinal cord. Most of the lesions are asymptomatic. These lesions are associated with epilepsy. Hemorrhage can be a presenting feature. It can be solitary or multiple.
Multiple lesions (>5 in number with a positive family history) can be seen in familial cerebral cavernous malformation.
It can be associated with developmental venous anomalies (DVA). Hence, it is important to rule out the presence of a DVA in the setting of cerebral cavernoma.
