There is a large lobulated mass within the distal gluteus maximus near its insertion on the linea aspera, which invades the vastis lateralis and abuts the sciatic neurovascular bundle. This mass demonstrates predominately low T1 signal which is isointense to muscle and hyperintense on STIR, with scattered areas of fat signal. There is avid post-contrast enhancement of the lesion. No peri-tumoral edema is appreciated.
