Updates to Study Attributes

Findings was changed:

A defect within the cubital tunnel retinaculum measuring 5 mm in length (blue line, image A) with evidence of ulnar nerve fascicles outpouching through it measures 14 x 4 mm (yellow outline, image A).

Just distally there is partial nerve injury with loss of the medial portion of the nerve fascicles at the level of the cubital tunnel (red arrow, image B) followed by focal nodular circumferential thickening of the ulnar nerve just distal to the cubital tunnel measures 7 x 8 x 11 mm with circumferential of about 33 mm2 (in comparison with the average circumferential diameter of about 8 mm2) denoting central traumatic neuroma (white arrow, image C).

Post-contrast images show no abnormal enhancement.
