Surgical management of Aspergillus colonization associated with lung hydatid disease.

Colonization with Aspergillus sp. usually occurs in previously formed lung cavities. Cystectomy is a widely used surgical technique for hydatid lung disease that can also leave residual cavities and potentially result in aspergilloma. We present two cases of this rare entity and a case with Aspergillus sp. colonization of an existing ruptured hydatid cyst.
