Mucoid impaction after segmental resection of lung.

Lung segmentectomy is generally considered as a standard procedure in general thoracic surgery. Anatomical variations of pulmonary segmentation may, however, make it difficult to determine the precise area of resection during segmentectomy. Incomplete pulmonary sub-lobar resection may produce unusual radiographic features. Herein, we report a case of bronchial atresia after lung segmentectomy.
