Male, 18 years old. Posteromedial left leg and knee pain. Evaluate for stress reaction. Focal bone marrow edema and signal abnormality within the cortex of the mid tibial diaphysis compatible with a stress reaction. No corresponding abnormality on T1 imaging to indicate acute fracture. The remainder of the bone marrow signal is unremarkable. The overlying soft tissues and musculature are unremarkable. The contralateral leg is grossly normal.
Findings compatible with a stress reaction with microfracture of the mid left tibial diaphysis.
