CT and pathological features in renal parenchymal malakoplakia: a case report and review of the literature

Abstract

Renal malakoplakia is a rare form of chronic inflammatory granulomatous disease in the kidney. It occurs in adult patients with immunocompromised status or debilitating disease. In the present study, we reported a case of a 50-year-old woman with no underlying disease. This report describes the CT and pathological features of renal malakoplakia in a 50-year-old woman. Plain CT scan showed a large soft tissue mass at the middle and upper pole of the left kidney. Enhanced CT scan showed delayed enhancement in the solid part of the mass. Our results might provide some useful information for the diagnosis of renal parenchymal malakoplakia.

Zusammenfassung

Nierenmalakoplakie ist eine seltene Form der chronischen entzündlichen Granulomatose in der Niere. Es tritt bei erwachsenen Patienten mit immungeschwächtem Status oder schwächender Krankheit auf. In der vorliegenden Studie berichteten wir über einen Fall einer 50-jährigen Frau ohne zugrunde liegende Krankheit. Dieser Bericht beschreibt die CT und pathologischen Merkmale der Nierenmalakoplakie bei einer 50-jährigen Frau. Die CT zeigte eine große Weichteilmasse an der mittleren und oberen Pol der linken Niere. Ein verbesserter CT-Scan zeigte eine verzögerte Verbesserung am festen Teil der Masse. Unsere Ergebnisse könnten einige nützliche Informationen zur Diagnose der Nierenparenchymalen Malakoplakie liefern.
