title: Benign Vascular Malformation at the Ischial Tuberosity.
abstract: A 31-year-old female student was referred to physical therapy with a chief complaint of proximal, posterior left thigh pain that began insidiously 12 months prior, and progressively worsened while training for a half-marathon. A mobile, soft mass was identified just inferior to the ischial tuberosity that was tender and painful to palpation, recreating the patient's chief complaint. Radiographic findings were negative for a suspected avulsion fracture at the ischial tuberosity. Therefore, the physician performed musculoskeletal ultrasonography, which revealed a superficial hypoechoic mass with vascular flow. Magnetic resonance imaging and a subsequent biopsy led to the diagnosis of a benign vascular malformation. J Orthop Sports Phys Ther 2016;46(7):607. doi:10.2519/jospt.2016.0410.
