Swyer-James Macleod Syndrome With Progressive Hyperinflation

Swyer-James Macleod syndrome (SJMS) is a rare disorder characterized by unilateral lung or lobar hyperlucency on chest radiographs. We present a case of SJMS with progressive enlargement of the bulla. A lobectomy was performed because the bulla in the right middle lobe had enlarged and compressed the upper and lower lobes, resulting in severe dyspnea. This treatment improved severe dyspnea and pulmonary function. Surgical resection is a viable option for SJCM patients experiencing short-term progression.
