20-year-old female with pain. Evaluate for stress fracture. Right tibia/fibula: The distal tibial diaphysis demonstrates abnormal bone marrow signal intensity with hyperintense signal to skeletal muscle on T2/STIR sequences and hypointense signal on T1-weighted sequences however not as hypointense as the adjacent skeletal muscle. This is compatible with marked bone marrow edema. There is mild surrounding periosteal edema as well. This is compatible with a stress reaction. We cannot identify a discrete fracture. There is associated edema in the surrounding soft tissues.Left tibia/fibula: There is bone marrow edema within the distal tibial diaphysis however to a lesser degree when compared to the right tibia. This is also compatible with a stress reaction with no discrete fracture identified. There is mild periosteal edema and edema within the surrounding soft tissues.
Bilateral tibial stress fractures as described above.
