Shadows of the bleeding joint: A radiologic exploration.

Hemophilia is a genetic disorder that manifests due to a deficiency of clotting factors. One of the most common complications is hemophilic arthropathy which results in bleeding into large joints causing hemosiderin deposition. Recurrent hemarthrosis causes joint destruction resulting in pain and a decreased range of movements. Radiological imaging is essential for staging, prognostication, and treatment protocol. X-rays show the extent of joint destruction and narrowing of joint space. Ultrasonography helps in visualizing tendons and joint effusion. However magnetic resonance imaging is the gold standard for staging hemophilic arthropathy. Management involves both medical and surgical intervention as per the level of joint involvement.
