Multifocal hydatid disease in a child.

One of the most serious helminth infections in humans with widespread occurrence is hydatid disease. Although the majority of the cases are referred in adults, many of them have to do with children. The hydatid cysts can occur in any organ of the human body and in rare cases in a combination of different sites. We present the case of a young boy with hydatid cysts in both lungs and in the upper pole of the left kidney. The rarity of this case is the unusual combination of the cyst development in these organs without the involvement of the liver.
