Pneumocystis carinii involvement of the liver and spleen: CT demonstration.

Patients with acquired immunodeficiency syndrome (AIDS) are subject to a variety of infections, including Mycobacteria avium intracellulare, cytomegalovirus, Cryptosporidium, and Pneumocystis carinii. Pneumocystis is most commonly associated with a potentially fatal pneumonia in AIDS patients. Other organ involvement by Pneumocystis is rare. We present a patient with hepatic and presumed splenic infiltration by Pneumocystis.
