Objective:
The purpose of the study was to evaluate the appearance of "cubital bursitis" on ultrasonography and CT and MR imaging. "Cubital bursitis" is a rare pathological condition involving a large swelling of the bicipito-radial or interosseous bursae located at the insertion of the distal biceps tendon on the radial tuberosity.
Design And Patients:
We report on five patients with "cubital bursitis" resulting from their work or sporting activities. All patients underwent an ultrasound and MR examination. CT scans were performed on two patients before and after contrast enhancement.
Results:
Ultrasound studies showed a fusiform anechoic or hypoechoic lesion. CT images showed the lesions but there were some difficulties in determining the exact extent of the bursae. MR imaging showed the enlarged bursae and their fluid content. Four patients each underwent a surgical procedure.
Conclusion:
Ultrasound and CT were effective in the evaluation of "cubital bursitis", but with some diagnostic difficulties. MR imaging is probably the method of choice for determining both the development of the bursae and their fluid content.
