Focal xanthogranulomatous pyelonephritis mimicking adrenal mass: Case report

Abstract

Xanthogranulomatous pyelonephritis is a rare form of chronic renal infection which is unknown etiology exactly. Xanthogranulomatous pyelonephritis is typically associated with an obstructing calculus. Because of the nonspecific findings of ultrasonography, computed tomography and magnetic resonance imaging can be selected diagnostic modalities to show the extrarenal extension of the disease. However, it may be difficult to distinguish focal involvement of xanthogranulomatous pyelonephritis from renal tumors and sometimes diagnosis can only be made after nephrectomy. In this article we present a case of xanthogranulomatous pyelonephritis mimicking adrenal mass and histopathologically diagnosed.

Adrenal kitleyi taklit eden fokal ksantogranülomatöz pyelonefrit: Olgu sunumu

Abstract

Ksantogranülomatöz pyelonefrit (KGP) etiyolojisi tam olarak bilinmeyen ve nadir gö­rülen kronik renal inflamasyondur. Tipik ola­rak taşa bağlı obstrüksiyon zemininde gelişir. Ultrasonografi (USG) bulgularının nonspe­sifik olması sebebiyle bilgisayarlı tomografi (BT) ve Manyetik Rezonans Görüntüleme (MRG) hastalığın tanısı ve preoperatif plan­lamada ekstrarenal uzanımının gösterilme­sinde seçilebilecek diagnostik modalitelerdir. Ancak fokal tutulum gösteren KGP’i böbrek tümörlerinden ayırt etmek zor olabilir ve ba­zen tanı yalnızca nefrektomi sonrası konula­bilir. Bu yazımızda adrenal kitleyi taklit eden ve histopatolojik olarak ksantogranulomatöz pyelonefrit tanısı alan olgu sunulmuştur.
