Proximal tibia lesion Again seen is abnormal marrow signal within the proximal diaphysis of the right tibia the extent of which is similar to the prior exam. No discrete fracture line is evident. The abnormal signal appears to be centered near the insertions of the semitendinosis, gracilis, sartorius and tibial collateral ligament.There is diffuse soft tissue edema particularly along the posteromedial and anterior portions of the lower extremity. There is surrounding muscular edema at the level of the abnormal marrow signal as well. The marrow signal of the fibula is normal.
