Abstract

Xanthogranulomatous pyelonephritis (XGP) is a rare type of chronic bacterial nephritis, which rarely involves the invasion of adjacent organs or the formation of fistulas due to tissue-destructive granulomatous reactions. Although the invasions of various adjacent organs have been reported in several cases of XGP, MRI data on their features are limited. MRI has a better soft-tissue resolution than CT. Thus, it can identify the extent of extrarenal involvement in advanced XGP, and the findings can be used in treatment planning. Herein, we report a rare case of XGP with nephropleural fistula formation diagnosed using CT and MRI.

황색육아종성 신우신염은 드문 형태의 만성세균성 신감염으로, 조직 파괴적인 육아종성 반응으로 인해 드물게 인접한 장기를 직접적으로 침범하거나 누공을 형성할 수 있다. 황색육아종성 신우신염이 인접 장기를 침범한 다양한 경우가 보고되어왔으나 자기공명영상의 보고는 매우 드물다. 자기공명영상은 전산화단층촬영보다 우수한 연부조직 해상도를 가져 황색육아종성 신우신염의 파급 범위를 정확히 파악하여 치료 계획을 세우는 데 도움이 될 수 있다. 우리는 전산화단층촬영과 자기공명영상으로 황색육아종성 신우신염의 신장-흉강 누공 형성을 진단한 드문 증례를 경험하였기에 이를 보고하고자 한다.
