From: Overuse-related instability of the elbow: the role of CT-arthrography
Professional tennis player with chronic medial elbow pain, exacerbated during serve, not responsive to medical and physical treatments. MRI coronal fat-suppressed T2-weighted images (a) show a high-intensity signal at the anterior bundle (A-MCL), suggestive of partial tear (black arrows). CT-arthrography reformatted images along the major axis of the anterior bundle (b) demonstrate a thickened but continuous ligament (white arrows). US scan prior to contrast agent injection (c) confirms diagnosis by showing a thickened, hypoechoic ligament with irregular margins, although regularly inserted (yellow arrows)
