Aspergilloma in a hydatid cavity

Fungal colonization by aspergillus usually occurs in pre-existing lung cavities mostly due to post-tubercular sequelae. Colonization of a hydatid cavity is very rare. We hereby report this unusual co-infection in a 55 years old diabetic male patient who was diagnosed pre-operatively and was managed with surgery, anti-fungal agents, and anthelminthics. The possibility of this co-infection should make clinicians more vigilant in managing hydatid cysts in diabetics and immunocompromised, as they may have concomitant fungal infestation of the hydatid cavity.
