Hydatid disease commonly involves liver and lungs, although any organ can be involved. We report a case of primary renal hydatid cyst without the involvement of liver or lung, an extremely rare occurrence, with an incidence of 2 to 3% only. A 35-year-old male patient presented with right flank pain since 1 month. Ultrasonogram showed a large mass of 8×6×6 cms3 in the lower pole of the right kidney with cystic, enhancing solid components and calcified areas. This was of concern for a renal cell carcinoma. The patient underwent laparotomy with cyst excision and marsupialization. On gross examination the large cyst consisted of multiple fluid filled transparent cysts. Histopathology showed a laminated hyaline structure. Also seen was thick fibrocollagenous tissue, fibrosis, calcification and chronic inflammatory infiltrate comprised of lymphocytes and eosinophils.\r\nThis case report highlights that the renal hydatid cyst is often asymptomatic with non-specific clinical features. Only in 10 to 20% of the cases, rupture of the cyst into the collecting system can result in hydatiduria, the pathognomonic sign of renal hydatid cyst. \r\n
