case_images: Chest computed tomography (CT) taken after chest drainage showed bilateral PTX and bilateral cystic changes in the lung parenchyma, predominantly in the upper lobes (Fig. 2a). However, her pulmonary lesions progressed, and the number of bullae gradually increased (Fig. 2b-c). CT showed extensive bullae in the right lobe, which exerted a mass effect on the surrounding lung parenchyma, causing a left mediastinal shift (Fig. 2d). Although she was doing well immediately after the operation, on the tenth postoperative day, she developed a tension bulla in the left lung (Fig. 2e). Chest X-ray and CT suggested return of the right bulla and mediastinal shift (Fig. 2f), and reoperation was performed. Although she experienced no additional episodes of symptomatic PTX and tension bullae, there was evidence of some residual PTX on a follow-up CT scan (Fig. 2g). During the 12-month follow-up, the pulmonary lesions also showed a tendency for improvement (Fig. 2h).

case_images: Under thoracoscopic view, multiple bullous lesions were found to occupy most of the right upper and middle lobe (Fig. 3a). Emergency thoracoscopy-assisted resection of the bullae and ligation of pulmonary cysts to prevent the occurrence of PTX were performed (Fig. 3b). Emergency thoracotomy with plication of the bulla was performed (Fig. 3c).
case_images: a: Lung (Hematoxylin-eosin stain, X 20) shows a proliferation of Langerhans cells, which show elongnated kidney-shaped nuclei. Immunohistochemistry revealed CD1a and S-100 positivity. b: Repeated lung biopsy specimen showing CD1a negativity (X 10), suggestive of no active LCH.
