title: [Ultrasound findings of hamstring hematoma in a patient taking anticoagulants].
abstract: A patient started anticoagulation for secondary prevention of stroke, achieving a prothrombin time-international normalized ratio within the optimal therapeutic range. The patient subsequently complained of pain in the left thigh on hospital day 25, and ultrasonography showed a large intramuscular hematoma in the left hamstring. The intramuscular hematoma gradually reduced without surgical intervention. Ultrasound examination plays an important role in precisely diagnosing intramuscular hematoma and monitoring changes in hematoma size.
