[Computed tomography findings of pulmonary benign lesion in the peripheral region].
We evaluated computed tomography (CT) images in 22 cases of pulmonary granulomas less than 2 cm in diameter which preoperative diagnosis was difficult. In these lesions, air-containing type, irregular undulation of margin, pleural indentation, accompanying shadow and involvement of pulmonary artery was observed on CT images. The accompanying shadow and the absence of pulmonary vein relate to the lesion may have relevance in pulmonary benign lesion.
