Sonography of multifocal hydatidosis involving lung and liver in a female child.

Hydatid disease, caused by Echinococcus granulosus, is a zoonotic infection encountered worldwide. Though involvement of the liver and lungs is quite common, pelvic involvement is rarely reported, with the incidence being 0.2-2.2 %. Ovarian and broad ligament hydatids are rare entities and are usually seen after rupture of a hepatic hydatid cyst. These cysts are usually asymptomatic, and a high index of clinical suspicion coupled with unequivocal imaging findings is required to make an accurate and timely diagnosis. We present a case of multifocal hydatid disease in a female child involving the lungs and liver and provide an account of the quintessential radiological findings.
