Hydatidosis is a parasitic zoonosis caused by Echinococcus Granulosus, its life cycle includes dogs, sheep and others; liver involvement is the most frequent (65%-75%), followed by the lung (10%-25%), in Peru the pulmonary location is 60%. Its signs and symptoms are produced by the mass effect, its superinfection or anaphylactic reactions secondary to its rupture. We present the case of a 24-year-old insulin-dependent patient with type I diabetes mellitus, hypertension and diabetic retinopathy with bilateral pulmonary hydatidosis. A cystectomy was performed without complications and a lobectomy that was complicated with admission to the ICU until the death of the patient. Diabetes mellitus causes a state of immunosuppression which caused the advanced state of the patient's parasitosis, as well as being related to multiple intra- and postoperative complications and even leading to the death of the patient.
