Sharply delineated lession with very high signal on T2 and avid enhancement from the periphery to the center. Non-enhancing areas probably due to thrombotic material.
This type of lesion is also labeled as a cavernous hemangioma in the pertinent literature. However unlike infantile hemangiomas, it is a congenital malformation, that does not regress spontaneously.
