a The ulnar nerve (A) is of normal calibre but is displaced out of the cubital tunnel due to underlying hypoechoic collection (C) within the joint cavity. b T1-weighted axial image at the level of cubital tunnel shows hypoechoic ulnar nerve (yellow arrow) with surrounding isointense significantly thickened synovium (red arrows). c PD FS image shows isointense ulnar nerve (yellow arrow) with normal calibre with surrounding hyperintense synovial thickening (red arrows) and minimum joint effusion. On further laboratory investigation, the patient was diagnosed to be a case of rheumatoid arthritis
