A 42-old-woman with tingling and numbness in the ulnar side of the right hand. A 42-old-woman with tingling and numbness in the ulnar side of the right hand. Axial T1 (A) and T2 SPAIR (B) images show a hyperintense ulnar nerve (long arrows) entrapped at the cubital tunnel due to focal fibrosis (short arrows) related to previous injury. No denervation atrophy was seen at the time of imaging, and clinical as well as electromyography findings were in keeping with neurapraxia. A. Chhabra et al.
