Left-sided ICC is noted with the tip located peripherally next to the horizontal fissure, with a small associated pneumothorax. Minor associated subcutaneous emphysema associated with the ICC.
A large emphysematous portion of the most of the left upper lobe is demonstrated with lung markings extending into the apex, consistent with congenital lobar emphysema. Adjacent portions of the lower aspect of the left upper lobe are collapsed. No mediastinal shift. A band of plate atelectasis traverses the apical segment of the left upper lobe. The lungs are otherwise normal.
Heart and mediastinum are within normal limits for non-contrast examination. No lymphadenopathy. Bones and upper abdominal viscera are normal.
Impression
Large emphysematous portion of most of the left upper lobe consistent with congenital lobar emphysema. ICC is well positioned and associated with a small pneumothorax which is most likely associated with insertion of the catheter.
