Adenovirus infection is commonly associated with self-limited respiratory and gastrointestinal illnesses. However, infection in immunocompromised individuals, such as transplant recipients, can cause severe life-threatening illness including pneumonitis, hemorrhagic cystitis, nephritis, hepatitis and enterocolitis. In orthotopic liver transplant recipients, adenovirus viremia can cause hepatitis leading to marked transaminitis, allograft loss, and death. Although hepatic abscesses mediated by adenovirus have been described in other immunosuppressed patient populations, it has very rarely been described in liver transplant recipients. Here, we report two adult cases of hepatic abscesses following liver transplantation secondary to adenovirus infection and describe the successful treatment of these patients. Adenovirus should be considered as an uncommon etiology of hepatic abscess and unexplained fevers in adults following liver transplantation.
