Reason: evaluate bilateral hamstring origins History: pain with sitting at ischial tuberosity BONE MARROW: No bone marrow signal abnormality is identified.SOFT TISSUES: There is diffuse fatty infiltration of the imaged musculature of the pelvis including the paraspinal musculature. There is a partial thickness tear of the right hamstring tendon at the level of its origin off the right ischial tuberosity. There is partial thickness tearing of the left hamstring, involving both the conjoined and semimembranosus tendons, with approximately 2 cm retraction of the proximal tendon fragment. Additionally, there is a 1.5 cm round focus of fluid signal intensity within the left quadratus femoris muscle at the level of the myotendinous junction which may represent an interstitial tear. There is an additional smaller rounded focus of fluid signal intensity is identified within the distal fibers of the quadratus femoris muscle proximal to its insertion on the femur which may also represent an additional interstitial tear.JOINTS: Mild osteoarthritis affects the hips bilaterally. There is a small amount of fluid within both hips which is not necessarily of any clinical significance. There is a subcentimeter focus of fluid signal intensity within the superior acetabulum which may represent subchondral cyst formation. Severe degenerative disc disease affects the imaged lower lumbar spine.ADDITIONAL
1. Partial thickness tearing of both of the hamstring tendons at the level of their origin on the ischial tuberosity, left greater than right, with slight retraction on the left as described above. Interstitial tearing of the quadratus femoris muscle on the left. 2. Nonspecific signal abnormality within the posterior aspect of the right apex of the peripheral zone of the prostate gland. Correlation with PSA is recommended. Other findings as described.
