Carpal Tunnel Syndrome in Aberrant Muscle Syndrome: A Case Report and Review of the Literature

J Hand Surg Asian Pac Vol. 2018 Jun;23(2):290-293. doi: 10.1142/S2424835518720207.

Abstract

Aberrant Muscle Syndrome (AMS) is a rare congenital hand difference that is characterised by unilateral non-progressive muscular hyperplasia. The aetiology of aberrant muscle syndrome is not known, but a recently published case has shown a somatic PIK3CA activating mutation in a patient with AMS. Carpal tunnel syndrome (CTS) in children is rare. The most common causes are the mucopolysaccaridoses but space-occupying lesions have also been reported to cause CTS in children. We report the first case of CTS in a child with AMS successfully treated with open carpal tunnel release and excision of aberrant muscles.
