A rare ultrasound case report: intramuscular tear of the sartorius muscle

摘要

Abstract We report a case of a 65-year-old male patient who presented with localized swelling and lump in the proximal third of the upper thigh. Most common upper thigh injuries involve the quadriceps muscle group associated with football injuries; however, in rare incidents certain forceful intrinsic injuries can cause intramuscular tear of the sartorius muscle. This is a rare case of spontaneous muscle rupture in an elderly patient with no history of recent sporting activity. Ultrasound provides a cost-effective, dynamic evaluation of the anterior upper thigh muscles to differentiate between chronic and acute phases of injury.
