- Abstract
Hereditary neuropathy with liability to pressure palsy (HNPP) often manifests via peripheral nerve entrapment including median nerve compression at the carpal tunnel. However, there are few reports on surgical interventions for focal compression of the median nerve at the wrist in patients with HNPP. We report a case of a patient with HNPP who improved clinically, electrophysiologically, and ultrasonographically after carpal tunnel release (CTR). A 56-year-old woman presented with an 18-month history of pain in both thumbs. Nerve conduction study (NCS) revealed bilateral median neuropathy at the wrist. Ultrasonography demonstrated a markedly increased cross-sectional area (CSA) of both median nerves. Gene analysis revealed a deletion of the PMP22 gene. She received bilateral CTR. Follow-up NCS at one year demonstrated the improvement of motor and sensory conduction; follow-up ultrasonography revealed significantly reduced CSA. Our case suggests that surgical decompression can be applicable to well-selected patients with HNPP.
