AVM
Axial and Coronal T1W (A,C)and STIR (B,D) sequences demonstrate a lobulated well defined lesion predominantly within the muscle belly of TFL, displaying T1 hypointensity and STIR hyperintensity. The mass is moderately heterogeneous on the STIR sequence. Following biopsy this was histologically confirmed as an arteriovenous malformation (AVM).
