Isolated Renal Hydatid Cyst Misdiagnosed and Operated as a Cystic Renal Tumor

Abstract

Objective: The aim of this work is the presentation of a case of isolated renal hydatid cyst with novel findings and an unusual surgical scenario. Clinical Presentation and Intervention: A 54-year-old female patient presented with left loin pain and a palpable left renal mass. Imaging described a well-demarcated left renal cystic lesion with a double-layer wall. Radical nephrectomy was performed due to the possibility of malignancy. On retrograde revision, the double-layer wall represented the detached germinative membrane of a hydatid cyst that was confirmed by histopathology. Conclusion: Isolated renal hydatid cyst could be misinterpreted as a renal tumor. It should be considered in the differential diagnosis of renal cystic lesions.

Isolated renal hydatid disease: laparoscopic approach to an uncommon entity (case report)

“…Renal hydatid cyst may mimic renal cell carcinoma, renal abscess or complex benign cysts like renal lymphangioma, angiomyolipoma etc. [ 3 , 4 ]. There are several reported cases where the renal hydatid was misdiagnosed as a malignant tumor and a radical surgery was performed [ 4 - 6 ].…”

“…[ 3 , 4 ]. There are several reported cases where the renal hydatid was misdiagnosed as a malignant tumor and a radical surgery was performed [ 4 - 6 ]. Bosniak renal cyst type 2F and 3 often resemble renal neoplasm and cause diagnostic dilemma ( Figure 4 , Table 1 ).…”

Primary hydatid cyst looked like renal cell carcinoma: case report

“…The risk in this case was to perforate the cyst and induce a fatal anaphylactic shock. In the literature, many cases of isolated renal hydatid cysts being misdiagnosed have been reported and operated as renal tumors [ 5 , 6 ]. The challenge is to avoid the spillage of the content of the cyst.…”

Renal echinococcosis mistaken for a cystic tumor of the kidney

“…Компьютерная томография более чувствительна в выявлении дочерних кист, мелких кальцинатов, внутрикостного газа и более информативна для предоперационного определения анатомической локализации. Интерпретация образования как кистозная опухоль почки в данном случае является диагностической ошибкой [9][10][11].…”
