Cavernous Angiomas and Venous Angiomas
In up to 30% there is a coincidence of CCM with a venous angioma, also known as a developmental venous anomaly (DVA). These lesions appear either as enhancing linear blood vessels or caput medusae, a radial orientation of small vessels that resemble the hair of Medusa from Greek mythology. These lesions are thought to represent developmental anomalies of normal venous drainage. These lesions should not be removed, as reports of venous infarcts have been reported. When found in association with a CCM that needs resection, great care should be taken not to disrupt the angioma.
Left Orbital Cavernous Hemangioma
Frontal and temporal lobes are the most common sites of occurrence, and 80-90% of the lesions are supratentorial.
