Case Report: Hepatitis and autoimmune hemolytic anemia induced by EBV-associated infectious mononucleosis

Year: 2026

Type: article

Abstract: Epstein-Barr virus (EBV) typically causes infectious mononucleosis, but in rare cases, it may lead to complications such as autoimmune hemolytic anemia (AIHA) and hepatitis. We report the case of an 18-year-old previously healthy female who presented with jaundice, red urine, and arthralgia. Laboratory workup revealed direct hyperbilirubinemia, elevated transaminases, and a direct antiglobulin test positive for IgG (negative for C3d), consistent with warm autoimmune hemolytic anemia in the context of EBV infection. Imaging ruled out biliary obstruction. The patient was managed conservatively, with cautious steroid use, and demonstrated clinical improvement without progression to hepatic failure. This case underscores the importance of recognizing atypical hepatic presentations of EBV and carefully managing overlapping autoimmune complications.
