Diffuse Renal Cortical Echogenic Foci in a Patient With AIDS: A Case of Pneumocystis Nephritis

Pneumocystis jirovecii is ubiquitous in the environment and is best known as the cause of Pneumocystis pneumonia (PCP) in immune-suppressed hosts. Extrapulmonary P. jirovecii is a rare complication of this opportunistic infection primarily seen in patients with immune-deficient states. Nephritis due to P. jirovecii was first described by Bargman in 1991 in a patient with atypical nephrocalcinosis found on conventional radiography. This case report presents a patient with Pneumocystis nephritis and describes the sonographic appearance as well as the advantages of sonography in the early detection of this uncommon condition.
