[Coexistence of Pulmonary Aspergillosis and Hydatidosis. Case report].

Hydatidosis is a zoonosis caused by the parasite Echinococcus granulosus and Peru is an endemic zone for this infection. We present the case of a 33-year old woman from the region of Ica who, during gestation, was diagnosed with liver and pulmonary hydatidosis. After gestation was terminated, she was referred with thoracic drainage tube, dyspnea, and thoracic pain in right hemithorax, with progressive course and tomographic image of thorax showing right posterior basal pulmonary cyst. The serological analysis was positive, the patient underwent surgical resection with histopathologic result as complex non-viable pulmonary hydatidic cyst and mycotic structure consistent with aspergilloma. The coexistence of these two diseases is rare and can mean potential threats for patients. The early diagnosis and treatment are vital to prevent possible complications such as massive hemoptysis or even invasive disease.
