MRI of retracted hamstring following complete avulsion

The patient is a 57-year-old male who was involved in a water skiing injury. The MRI of the thigh using a fast STIR sequence in the coronal plane (A, B) and proton density with fat saturation in the sagittal plane (C, D) demonstrate a completely detached and retracted hamstring injury. The retracted hamstring tendon is seen as redundant low signal structures distally (arrow). The retracted tendon is remote and detached from its insertion site at the ischial tuberosity (small arrowhead). A seroma (large arrowhead) is seen as a large high intensity homogeneous signal. Clot within the seroma (dashed arrow) is seen as intermediate signal.
