The patient is an avid bodybuilder and has noticed that his grip strength has gradually worsened in both hands with symptoms worse at the end of a long workout. The patient has a past medical history of anabolic steroid use in high school. His current medications include a multivitamin, fish oil, and whey protein supplements. On physical exam, you note a muscular young man with male pattern hair loss. The patient has a loss of sensation bilaterally over the volar surface of the 4th and 5th digits and over the medial aspect of the volar forearm. The patient has 35 grip strength of his left hand and 25 grip strength of his right hand. There is also notable weakness of finger adduction and abduction. The rest of the patients physical exam is within normal limits.Which of the following is the most likely diagnosis?? A: Brachial plexopathy, B: Cubital tunnel compression, C: Guyons canal compression, D: Carpal tunnel syndrome, E: Posterior interosseous nerve compression,  <response>: This is a patient with progressive bilateral hand weakness and sensory changes localized to the ulnar nerve distribution, worse on the right side. The key findings are weakness and sensory loss in the 4th and 5th digits and medial forearm, which localizes the lesion to the ulnar nerve. The differential diagnosis includes cubital tunnel compression, Guyons canal compression, and other causes of ulnar neuropathy. However, the history of bodybuilding and anabolic steroid use in high school raises suspicion for tardive ulnar neuropathy, a condition that can occur with prolonged anabolic steroid use. The sensory and motor exam findings are classic for ulnar neuropathy. Of the choices given, cubital tunnel compression is the most likely diagnosis, as this is the most common site of ulnar nerve compression in the arm. The other choices can be ruled out based on the distribution of weakness and sensory findings.B: Cubital tunnel compression
