CASE 82: MRI BRAIN

35F convulsions, not investigated earlier.

Findings reveal an intra axial right, high parietal lesion with old and chronic hemorrhage within, within minimal surrounding edema. No significant contrast enhancement is noted.

DIAGNOSIS

Venous Angioma

 

Discussion

Venous angiomas can be distinguished from the common arteriovenous malformation (AVM) by the convergence of medullary veins from various directions and by the presence of normal brain parenchyma between them, features not present in the A VM. Draining veins may not be seen sometimes.

Vascular hamartomas with a remarkable angiographic resemblance to venous angiomas have been described with the diagnosis of telangiectases and cavernous hemangiomas.
