Bilateral agenesis of the long head of the biceps tendon

Bilateral agenesis of the long head of the biceps tendon

The congenital variations of the biceps brachii muscle are seen quite frequently, however, the agenesis of the long head, is extremely rare. Diagnosis can be difficult, especially in cases with traumatic shoulder pain. In this paper, a 25-year-old female patient with bilateral biceps tendon agenesis is presented. Shoulder examination was negative for any signs of a traumatic biceps injury. Magnetic resonance imaging revealed congenital absence of the long head of biceps tendon and bilateral shallowness of the intertubercular groove.
