Isolated renal hydatid cyst managed with partial nephrectomy.

A 35-year-old woman presented with left upper quadrant abdominal pain for one year. There were no gastrointestinal symptoms. Ultrasonography showed a cystic lesion in the left renal area. A computed tomography scan revealed a 10.5 cm × 9 cm × 8.5 cm heterogeneous cystic mass, occupying the superior pole of the left kidney. There were areas of calcification in the lower portion of the cyst. The cystic mass was abutting the tail of the pancreas, and was wedged between the splenic hilum, the upper pole of the left kidney, and the tail of the pancreas. There were no other similar intra-abdominal lesions.
