Acute cytomegalovirus cholecystitis following renal transplantation.

Solid organ transplant recipients are at risk of infection from cytomegalovirus (CMV). A wide range of disease is associated with CMV infection and we report two cases of CMV cholecystitis in patients following renal transplantation. Both patients presented with severe hemorrhagic cholecystitis, which required immediate resuscitation and emergency cholecystectomy. The diagnosis of CMV infection was confirmed in both cases using CMV-specific staining of the gallbladder. The diagnosis of CMV cholecystitis must be considered in all patients with upper abdominal pain after renal transplantation.
