AN EXTREMELY RARE PRESENTATION OF PRIMARY RETROPERITONEAL RETROVESICAL HYDATID CYST AS OBSTRUCTIVE UROPATHY

Primary retroperitoneal hydatid cyst is extremely rare and only few case reports exist in literature. We present a case report of retrovesical hydatid cyst mimicking retroperitoneal cystic tumor presenting as life threatening obstructive uropathy with raised serum creatinine. The patient was treated with initial bilateral percutaneous nephrostomy drainage and later cystectomy. The case report points to difficulty in diagnosis, problems in management and potentially life threatening nature of disease.
