Myofibroma of the distal biceps brachii tendon: imaging findings of a rare entity
摘要
The case highlights the complementary role of dynamic ultrasound and magnetic resonance in an atypical cause of anterior elbow pain. Ultrasound revealed a hypoechoic mass adjacent to the distal biceps tendon and enabled assessment of its close relationship with the tendon by demonstrating movement synchronous with tendon excursion. Although establishing the final diagnosis was challenging, it was ultimately achieved through histological examination.
