Intrapulmonary bronchogenic cyst: CT and pathologic findings in five adult patients.

OBJECTIVE The purpose of our study was to describe the CT and pathologic findings of intrapulmonary bronchogenic cysts in five adult patients. CONCLUSION Intrapulmonary bronchogenic cysts in adults appear on CT as well-defined ovoid lesions with the attenuation of soft tissue or water, similar to their mediastinal counterparts. Associated with these cysts are areas of mosaic low attenuation and bandlike linear attenuation representing histopathologically confirmed emphysema and bronchiolization or fibrotic change or both in the surrounding lung.
