Tibial lesion There is a bony exostosis of the medial portion of the proximal left tibial metadiaphysis. There is clear extension from the marrow (series 8 image 60/80 and series 4 image 7/23) without evidence of a soft tissue mass. There is no evidence to suggest malignancy or osteomyelitis. The marrow signal of both the exostosis and the accompanying tibia is normal. There is no abnormal enhancement.There is diffuse subcutaneous edema of the lower extremity, particularly anteriorly. There is no evidence of a focal fluid collection. There is mild diffuse fatty atrophy of the musculature.
