[Patient with hypertransaminasemia and mononeuritis multiplex]. / Paciente con hiperaminotransferasemia y mononeuritis múltiple.

ABSTRACT

We present the case of a 57-year-old man with mononeuritis multiplex and high transaminase levels. After investigations, the patient was diagnosed with acute hepatitis B infection and polyarteritis nodosa (PAN). The symptoms of PAN are nonspecific. Nervous system involvement in the form of mononeuritis multiplex can be one of the forms of presentation. PAN is one of the extrahepatic manifestations of hepatitis B, but since the introduction of the hepatitis B vaccine, its incidence has markedly declined. After 1 year of follow-up, the patient is asymptomatic following treatment with antiviral drugs and steroids.
