Ossification common hamstring tendon

Case contributed by Dr Chris O'Donnell

Presentation

Incidental finding on pelvic radiograph for hip pain

Patient Data

Age: 70
Gender: Male

Unusual ossification parallel to the proximal femur (arrowed)

CT

CT for clarification of left x-ray findings

Well-defined ossification in the common hamstring tendon (biceps and semitendinosus) on the left.  Minimal change in a similar location on the right.

Case Discussion

Dystrophic ossification in tendons is well recognised (eg Achilles), however, the location and extent in this case is very unusual.  Note how the calcification is well ossified (ie looks like bone).  It is presumed to have occurred due to previous injury some time ago (? years).
