OBJECTIVE: The purpose of our study was to describe the sonographic appearance of cubital bursitis in three patients and to illustrate the use of sonographic guidance for therapeutic injections. CONCLUSION: Cubital bursitis, a rare but painful condition of the elbow, can be diagnosed with sonography. Cubital bursitis is seen as distention of the bicipitoradial bursa in the proximal forearm, occasionally with fluid or complex synovial debris in more severe cases. Power Doppler imaging can aid in providing information about active inflammation. Two patients in our series were treated using sonographically guided decompression of the bursa and steroid injection with good clinical results.
