Click Axial T1 weighted sequence (TR 648, TE 13) demonstrate a large mass posterior to the elbow. It is poorly marginated and characterized by intermediate signal intensity on both T1 and T2 weighted sequences. There is peripheral enhancement around the lesion follwoing contrast. The lesion extends both medially and laterally around the elbow but it is not definitely contiguous with the joint space altough it abuts the margin of the joint capsule on all sides. There is some abnormally increased marrow signal very mild and vaguely seen in the humerus, radius and ulna but the cortex appears to be intact. There is what appears to be some erosion of the lateral epicondyle.
