Isolated hydatid cyst of kidney.
OBJECTIVE
Hydatid cyst of the kidney is a very rare condition caused by the larval stage of Echinococcus granulosus. We report a case of isolated hydatid cyst of the kidney.


METHODS
A 32-year-old male patient presented with vague pain in the left lumbar region of 3 months' duration. Abdominal examination demonstrated a palpable mass in the left flank. The routine laboratory findings were normal. Radiologic studies showed a soft-tissue mass in the mid-portion of the left kidney measuring 115 x 130 mm.


RESULTS
We performed kidney-sparing pericystectomy, and the cyst was removed intact. The histopathologic findings confirmed the diagnosis.


CONCLUSIONS
In general, surgery is the treatment of choice for a hydatid cyst of the kidney, and kidney-sparing surgery is the most appropriate treatment whenever possible.
