Abstract

Hepatitis E virus (HEV) infection is a common cause of acute hepatitis in India and other developing countries. The data regarding the neurologic manifestation of HEV infection are limited. The neurologic disorders including Guillain-Barré syndrome, polyradiculopathy, neuralgic amyotrophy, encephalitis, bilateral brachial neuritis, ataxia/proximal myopathy, and acute transverse myelitis have been described. Bell's palsy and other cranial nerve involvement in hepatitis A virus (HAV) and HEV infection are rare. We present the second case of Bell's palsy associated with HEV.
