Abstract
Arteriovenous malformations (AVMs) of the temporalis muscle are an extremely rare subgroup of head and neck AVMs. The authors report two cases presenting with temporal fossa tumor-like lesions. MRI demonstrated enlargement of the temporalis muscle with hypointensity on T1, hyperintensity on T2 and moderate contrast enhancement. Angiography shows slow arteriovenous shunting with a dense capillary blush of the entire muscle before draining into facial veins. The arterial supply is characteristic of being restricted to the temporalis muscle.
