Neuralgic Amyotrophy Associated with Cytomegalovirus Infection: A Case Report

ABSTRACT

Neuralgic amyotrophy (NA) is a peripheral neuropathy, primarily involving the brachial plexus. There is a relation between antecedent infection and NA. A few cases of NA after infections such as Epstein-Barr virus, herpes zoster virus, parvovirus, human immunodeficiency virus, Borrelia, and other infections have been reported. This case report describes a 26-year-old man with motor impairment after neuropathic pain with preceding mild flu-like symptoms whose laboratory studies revealed evidence of cytomegalovirus (CMV) infection. He was diagnosed with NA associated with CMV infection. In conclusion, CMV is a rare but possible pathogen of NA.
