title: Recurrent hemarthrosis in a boy with synovial hemangioma: a case report.
abstract: We describe an unusual case of hemarthrosis caused by a synovial hemangioma in an 11-year-old boy. The initial presentations were sudden onset of spontaneous knee swelling and painful sensation accompanied by limitation of joint movement. The patient had a history of recurrent swelling with spontaneous remission over the same location in the past year. In addition, diffuse cutaneous hemangioma since infancy was also noted. Synovial involvement of a cutaneous hemangioma was confirmed by multidetector computed tomography and arthroscopy. The patient was started on oral corticosteroid and β-blocker. No recurrence was noted on multidetector computed tomographic images or clinical examination at the 2-month follow-up.
