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.
