Imaging bicipitoradial bursitis: a pictorial essay.

Although bicipitoradial bursitis is not commonly seen, when it does occur, it can frequently lead to diagnostic difficulty, mimicking either a soft-tissue tumor or infection. Lack of awareness of this uncommon entity can lead to unnecessary anxiety or tissue biopsy. This pictorial essay discusses the normal anatomy of the bicipitoradial bursa and the spectrum of imaging findings of bicipital bursitis.
