The first patient, a 62-year-old with chronic cough and hemoptysis, underwent surgical resection after initial antibiotic therapy for infectious pneumopathy. Imaging revealed a cystic lesion in the left upper lobe, with a calcified hepatic cyst also detected. Surgical exploration led to an unexpected diagnosis of pleomorphic lung carcinoma.

In the second case, a 69-year-old woman with chronic cough was found to have a ruptured hydatid cyst in the lower left lobe. Surgical intervention, guided by the lesion's appearance, revealed an adenocarcinoma of acinar architecture.

These cases emphasize the importance of considering various differential diagnoses for pulmonary cystic lesions, requiring a comprehensive evaluation including radiological findings, clinical symptoms, and medical history to guide appropriate management decisions.
