Intratendinous ganglion of the long head of the biceps tendon: US and MRI features (2010: 9b). Intratendinous ganglion.

We present a case report and literature review of the ultrasound (US) and magentic resonance imaging (MRI) features of an intratendinous ganglion originating from the long head of the biceps tendon. Intratendinous ganglia are very rare entities and intratendinous ganglion of the long head of the biceps tendon has only been described once. To the best of our knowledge, this is the first case report presenting the sonographic features of an intratendinous ganglion originating from the long head of the biceps tendon.
