From: Imaging in the diagnosis of ulnar nerve pathologies—a neoteric approach
a Grey scale ultrasound image shows a hypoechoic, significantly thickened ulnar nerve (ULN) in the cubital tunnel with underlying joint effusion (E) and cortical irregularity (CC). The medial epicondyle (ME) and olecranon process (O) forming boundaries of the cubital tunnel are also seen. b T2-weighted MR image of the patient shows hyperintensity of the ulnar nerve (yellow arrow) with surrounding arthritic changes—subchondral cyst (red arrow), marrow oedema with cortical irregularity (blue arrow) and joint effusion (red arrowheads). c Intra operative picture of the patient showing the thickened ulnar nerve (black arrow)
