Medial Tibial Condyle Stress Fracture-MRI

This is a case of a marathon runner with obscure pain and MRI shows evidence of altered signal intensity in the medial tibial condyle with hyperintense signal on T2 and STIR images along with linear hypointense area likely consistent with a medial tibial condyle stress fracture with associated bone bruise/marrow edema. Although stress fractures of the tibial diaphysis are common among athletes, the proximal tibial metaphysis is an unusual location for such injuries.  MRI scan has proved very sensitive for diagnosing stress fractures and provided a definite diagnosis in our case.
