ABSTRACT
Echinococcosis is a zoonotic epidemic parasitic disease, which is caused by the infection with larvae of Echinococcus in humans, and the disease is also known as hydatid disease. The liver and lung are the most vulnerable organs. Aspergillus is a saprophytic fungus. Aspergillus infection is common in patients with immune deficiency. Pulmonary echinococcosis complicated with Aspergillus infection is very rare in patients with normal immune function. It is a case report in the literature at home and abroad. A case of bilateral isolated pulmonary echinococcosis complicated with Aspergillus infection with normal immune function and no other accompanying diseases admitted to Lanzhou University Second Hospital is reported as follows, and literature review is conducted in combination with Chinese and foreign literatures, so as to provide some reference value for diagnosis and treatment of this kind of disease.
