Left hip pain. Evaluate for occult fracture, metastasis, AVN. There is no evidence of an occult fracture. Subchondral foci of decreased T1 signal along the bilateral superior femoral heads without associated increased T2 signal likely represent bone islands. Bone marrow signal is otherwise within normal limits without abnormal enhancement. A 20 x 9 mm ovoid lesion within the left gluteus medius muscle follows fat on all sequences and is compatible with an intramuscular lipoma.
1. No evidence of avascular necrosis, fracture, or metastases. 2. Left gluteus medius intramuscular lipoma.
