Sonography of benign palpable masses of the elbow.

The purpose of this pictorial essay is to show the sonographic appearances of benign masses found in and around the elbow, including fat-containing tumors, fibrous tumors, vascular lesions, selected skin lesions, and other miscellaneous lesions. Sonographic features, including the use of dynamic and color Doppler imaging, can be helpful in characterizing these masses and in narrowing the differential diagnosis.
