ABSTRACT
Rationale: Cystic echinococcosis (hydatid disease) is a parasitic infection of humans, but renal hydatid cyst is rare. It is even more uncommon to find hydatid cyst and renal cell carcinoma (RCC) synchronously in one kidney. Patient concerns: This report presents a 47 years old Iranian man with the chief complaint of lower abdominal pain. Abdominal ultrasound and computed tomographic scan was performed for more evaluation. Diagnosis: RCC was the most probable diagnosis, so he went under left total nephrectomy. Eventually, after histopathologic examination of the excised kidney, cystic echinococcosis came to the first line and papillary RCC was the second diagnosis. Outcomes and lessons: Diagnosis of hydatid cyst and RCC is mostly based on imaging, but, as we noticed in this case, distinguishing between these two may sometimes be difficult due to radiological similarities.

ABSTRACT
Hydatid involvement of the kidney accounts for only 2–4% of all cases of hydatid disease it is very rare and again primary involvement of the kidney without involvement of liver parenchyma or lung parenchyma that makes it extremely rare. The purpose of this article is to review the imaging features of hydatid disease of the kidney and thus show the role of radiography, excretory urography, sonography, CT, and MRI in the diagnosis of Hydatidosis. Hydatiduria accompanies only 10 to 20 % of all cases of renal Hydatidosis and usually microscopic ,here we are reporting a 65 years old female with abdominal lump in right hypochondriac region with pain on USG finding suggestive of hydatid cyst of liver with indentation and possible involving right kidney but MDCT suggest it is a primary right renal hydatid large exophytic cyst having multiple daughter cysts involving upper pole of kidney with breech in the cortex and it extends to involve right renal pelvis which indenting to inferior surface of liver
ABSTRACT
Hydatid disease is a zoonotic infection caused by Echinococcus granulosus, which belongs to phylum Platyhelminthes. It is endemic in many parts of the world including India. Though Hydatid disease commonly occurs in liver and lung no organ or tissue is immune in the body. When it presents in unusual sites Hydatid disease often poses a diagnostic challenge. A high index of suspicion, comprehensive radio imaging investigations are often required to evaluate these cases. In the study we have conducted for 4 years, we reported a total no of 7 Hydatid cases that presented at unusual sites. Most common rare presentation in our study was renal hydatid disease, 3 cases; and one each in pancreas, Spleen, peritoneum and pelvis.
