Hip pain. Question of sacroiliitis. BONE MARROW: Bone marrow signal is within normal limits.SOFT TISSUES: There is increased, somewhat speckled T2 signal within the proximal aspect of the left vastus lateralis muscle. This region is isointense to muscle on T1 sequences. JOINTS: The sacroiliac joints are normal. Bilateral hip joints appear normal. There is increased T2 signal around the greater trochanter of the left femur which may represent some degree of a bursitis.ADDITIONAL
Findings most likely represent an intramuscular hemangioma of the left vastus lateralis muscle. Another possibility is localized inflammation to the muscle. Plain film radiographs are recommended for further evaluation.
