Biceps Tendon in Short Axis View – Explained Clearly

The correct answer is: 

A) the biceps tendon is not in the middle of the groove

Full explanation: In the short axis view of the biceps tendon on the level of the intertubercular groove you can see that the biceps tendon is not in the middle of the groove. Also the tendon itself has quite an unusual shape, it is flattened, wide and medialised. It tends to almost lie on top of the lesser tubercle.

What do you do next?

Answer: While sliding down with the transducer more distally in the short axis view you see that the biceps tendon is medially dislocated and it seems like it is almost sitting on lesser tubercle.

Next you want to confirm this finding as well in the long axis view. Where you also see a medially dislocated biceps tendon.

Also a MRI was performed which also confirmed the diagnosis of a medially dislocated biceps tendon.
