Backgrounds: Bronchopulmonary sequestration (BPS) is a rare congenital anomaly of the lung that has two different types as intralobar and extralobar. In this study, we aimed to present six cases of intralobar sequestration with atypical findings in terms of feeding, drainage and, localization. Methods: Patients diagnosed with intralobar pulmonary sequestration in our clinic between 2015-2019 were evaluated retrospectively. Demographical features and atypical Computed Tomography (CT) findings of the patients were presented by literature. Results: Among 45 patients with intralobar sequestration, six ones (13.3%) (5 males and 1 female) with a mean age of 43.5±25.4 (0-78) years old) had atypical pulmonary findings on CT images. Atypical features regarding arterial supply was detected in 8.9%, venous drainage in 2.2%, location in 4.4%, radiological appearance ın 4.4% and co-existing lesion in 2.2% of the patient with intralobar sequestration. Conclusion: Typical and atypical features of pulmonary sequestration must be well-known for differential diagnosis of solid or cystic pulmonary lesions.
