Concurrent pulmonary sequestration and pulmonary hydatid cyst in a child: A case report

Pulmonary sequestration (PS) happens when an area of the lung receives its arterial blood supply from systemic circulation, resulting in a non‐functional lesion (Intralobar or extralobar). Hydatid cyst results from infection of the tapeworm Echinococcus. We report a case of hydatid cyst existed concurrently with intralobar PS. A 12‐year‐old girl presented with recurrent hemoptysis of 2 years duration. Serology for Echinococcus granulosus was positive. CT chest suggested intralobar PS in the right middle lobe, which was surgically removed. In conclusion, recurrent localized pulmonary infections should raise the suspicion of intralobar PS which may rarely coexist with hydatid cyst.
