Isolated renal hydatid cyst misdiagnosed and operated as a cystic renal tumor

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
