Viral myositis is commonly seen with influenza and COVID-19 infections. While it has been described with acute viral hepatitis, concomitant involvement of the peripheral nerves causing a neuromyopathy has not been reported. A 67-year-old man with acute hepatitis B infection developed a severe myalgia and lower limb weakness around 1 month into his illness. Investigations revealed a neuromyopathy and rhabdomyolysis. MRI whole body with short tau inversion recovery sequences showed scattered muscle hyperintensities in the upper and lower limbs. He was treated with intravenous immunoglobulin and improved. This is the first report of an acute neuromyopathy associated with acute hepatitis B viral infection and demonstration of muscle MRI abnormalities in this condition.
