Here are two cases seen in a day one showing cavernous angioma in the midbrain showing characteristic variegated "popcorn" appearance. The lesion shows signal supression on GRE because of blood products. Other case is a venous angioma with enhancing vascular channel, characteristic appearance is called as "medusa head appearance" in the left parietal region.
