    Abstract:
    BACKGROUND Vanishing lung syndrome (VLS), also known as idiopathic giant bullous emphysema, is a rare manifestation of chronic obstructive pulmonary disease (COPD) and usually occurs in middle-aged smokers. This report presents a 58-year-old female smoker with COPD and VLS who presented with spontaneous pneumothorax. The pneumothorax was managed with a chest tube and was later complicated by massive subcutaneous emphysema. CASE REPORT A 58-year-old woman with a past medical history of long-term smoking and COPD presented with worsening shortness of breath. Upon initial evaluation, she had tachypnea and hypoxia (SpO₂ 93%). Chest radiography revealed a new right-sided pneumothorax on top of extensive bullous disease, which the patient already had. The drainage of the pneumothorax was successful with a pigtail catheter. However, during the following night, after insertion of the pigtail catheter, the patient developed massive subcutaneous emphysema, which was confirmed with imaging. The patient remained hemodynamically stable, and diffuse subcutaneous crepitus was present on examination. The pigtail catheter was repositioned, resulting in complete resolution of the subcutaneous emphysema in the following 2 weeks. CONCLUSIONS This case highlights the importance of a timely diagnosis and management of the possible presentations and complications of VLS. Complications such as pneumothorax are life-threatening and require urgent management, taking precedence over the curative treatment for VLS, surgical bullectomy.
