Calf edema and pain There is increased signal throughout the medial head of the gastrocnemius and indistinctness of the proximal tendon. Scattered areas of low signal intensity may represent tendinous fragments. The lateral head of the gastrocnemius and remaining muscles and tendons of the lower extremity are intact. There is extensive subcutaneous edema and fluid within the lower leg with areas of hemorrhage within the proximal portion of the gastrocnemius.A small focus of marrow edema is noted within the lateral tibial plateau. Otherwise the marrow signal of the tibia and fibula are normal.
Ruptured tendon of the medial head of gastrocnemius with associated muscle tear and hemorrhage.
