Diagnosis: Bicipitoradial bursitis.
Discussion
Findings:
Peripheral enhancing T2 high and T1 low SI lesion is
located between the distal biceps tendon and the anterior part of the radial tuberosity,
extending to the proximal interosseous portion. Distal biceps tendon is
partially disrupted.
Differential Diagnosis: Complicated Ganglion, Biceps tendon rupture with hematoma,
Interosseous bursitis
Diagnosis: Bicipitoradial
bursitis.
Discussion:
The
bicipitoradial bursa is a thin and delicate structure lined by a synovial
membrane and is located between the distal biceps tendon and the anterior part
of the radial tuberosity. As the forearm moves from supination to pronation,
the radial tuberosity rotates from a medial to a posterior position. The biceps
tendon curls around the radius, compressing the interposed bursa. Medial to the
bicipitoradial bursa and lying in contact with the interosseous membrane is the
interosseous bursa
