Cytomegalovirus cholangitis after renal transplantation

Clinically significant cytomegalovirus cholangitis is well recognized in patients with AIDS but is less common in other groups of immunocompromised patients. The authors describe a 59-year-old man who had undergone renal transplantation in whom this condition developed, and they emphasize that this diagnosis should be considered in renal transplant patients presenting with biliary obstruction. Careful examination of biopsy material for cytomegalovirus inclusion bodies is necessary.
