Concomitant Pulmonary Cystic Echinococcosis and Aspergillosis in a Male Child.

Co-infection of cystic echinococcosis and aspergillosis is a rare finding. The patient was a 10-year-old boy complaining of chest pain and malaise with a cyst in the right lung who underwent surgical resection of the cyst. Medical therapy with albendazole was started for the patient with the initial clinical impression of cystic echinococcosis. Later, the microscopic evaluation revealed a laminated layer of cystic echinococcosis involved by acute angle branching hyaline hyphae with septate. Thus, the diagnosis of a cystic echinococcosis and aspergillosis co-infection was established. Surgery is the mainstay of treatment along with anthelminthic and anti-fungal therapy, especially in immunocompromised patients.
