We report the case of a 2-month-old female infant admitted for recurrent respiratory infections and acute respiratory distress. The initial chest radiograph suggested a pneumothorax; however, chest CT demonstrated a giant emphysematous bulla involving the right upper lobe, causing significant mediastinal compression, consistent with CLE. The patient underwent right upper lobectomy, and histopathology confirmed emphysematous changes with chronic nonspecific inflammation and hemorrhagic remodeling. Postoperative evolution was favorable. This case illustrates the diagnostic challenges associated with CLE, particularly its potential to mimic pneumothorax and prompt inappropriate invasive procedures. Radiological evaluation—especially CT imaging—plays a pivotal role in establishing a definitive diagnosis and guiding appropriate management.
