39-year-old female. Left anterior hip mass. Evaluate etiology. A marker was placed over the patient's palpable abnormality in the left anterior hip. No underlying soft tissue mass or pathologic enhancement on post-contrast sequences is evident. The lack of a discrete mass despite having a palpable abnormality could be explained by a nonencapsulated small lipoma, which could be occult on imaging.Bone marrow signal intensity and the musculature of the left hip are unremarkable. The acetabular labrum is grossly unremarkable.
