Aspergilloma in a pulmonary hydatid cyst: a case report.

The most common predisposing factor for aspergillomas is the presence of a pre-existing lung cavity secondary to tuberculosis, bronchial cysts and bullae, neoplasms, and pulmonary infarction. However, Aspergilloma within a hydatid cyst is a rare occurrence. A 52-year-old female was presented with chest pain and shortness of breath. Computerized tomography-guided fine needle aspiration (FNA) showed fragment of lamellated membrane of hydatid cyst in a background of amorphous debris. Surgical enucleation of the cyst revealed lamellated hyaline acellular ectocyst of hydatid cyst and collections of acute angle branching septate hyphae conforming to morphology of Aspergillus. Here we describe this rare entity of aspergilloma in a pulmonary hydatid cyst and discuss its management.
