Urinary tract malakoplakia with extension into the retroperitoneum with secondary gastrointestinal involvement.
A rare case of malakoplakia of the urinary tract with diffuse retroperitoneal extension is presented. Sonographically guided cytologic puncture revealed the pathologic diagnosis. The splenic flexure of the colon and the stomach appeared to be secondarily involved in the inflammatory retroperitoneal tumor. The relative role of the various imaging modalities in defining retroperitoneal extension of the disease is illustrated, with a special reference to computed tomography and endosonography. After antimicrobial treatment and left nephrectomy, partial regression of the retroperitoneal mass was documented.
