Reason: please include proximal femur soft tissue sarcoma History: new onset of pain Note is made of increased signal abnormality on fluid sensitive sequences along the posterior aspect of the left hip and thigh abutting the medial aspect of the hamstring musculature and vastus lateralis. There is minimal, if any, enhancement on postcontrast sequences, however, no nodular or masslike enhancement is seen. No focal masses are identified. Skin markers overlie the posterior aspect of the thigh, presumably corresponding to the patient's surgical scar. There is diffuse mild fatty infiltration of the imaged musculature of the left hip and thigh. There are multiple foci of metallic susceptibility artifact within the soft tissues along the posterior aspect of the thigh, presumably postsurgical in etiology. There is linear decreased signal abnormality within the subcutaneous tissue along the posterior aspect of the thigh likely representing postsurgical scarring. No bone marrow signal abnormality is identified. There is a small amount of fluid within the left hip which is likely of no clinical significance.
Minimally enhancing signal abnormality within the soft tissues along the posterior aspect of the left hip and thigh likely representing postsurgical change/granulation tissue. While no masslike enhancement is identified to suggest residual or recurrent disease, follow-up examination is recommended to evaluate for interval change, particularly given the lack of prior examinations for comparison.
