Chronic necrotizing pulmonary aspergillosis in an immunocompetent patient after the surgery of hydatid cyst.

Chronic necrotizing pulmonary aspergillosis (CNPA) is a condition caused by the ubiquitous fungus Aspergillus fumigatus in non-immunocompromised individuals. Numerous underlying conditions have been associated with CNPA. Tuberculosis, non-tuberculous mycobacterial infection and allergic bronchopulmonary aspergillosis (ABPA) remain the predominant risk factors for development of CNPA. Development of CNPA in echinococcal cyst cavities is very rare and the optimal therapeutic regimen and treatment duration have not been established. Here, we present a case of CNPA developed six years after the cystectomy operation of hydatid cyst and treated with voriconazole successfully.
