Biliary obstruction and cholestasis in AIDS: case report.

In summary, we have described a patient with AIDS and a previously unreported cause of biliary tract obstruction. The incidence of cryptococcal visceral lymphadenitis in patients with AIDS and disseminated cryptococcosis is unknown, but, if present, is probably clinically silent in most instances. However, in the differential diagnosis of abdominal pain and cholestasis in such patients, one should consider major biliary duct obstruction due to cryptococcal lymphadenitis.
