Lymphangioleiomyomatosis with a Giant Bulla: Report of a Case

We report a case of lymphangioleiomyomatosis (LAM) with a giant bulla. A 33-year-old woman was referred to our department for treatment of dyspnea. Chest computed tomography showed a giant bulla with many smaller bullae. To obtain a definitive diagnosis and relieve the dyspnea, we performed a lung biopsy and bullectomy, after which her symptoms and pulmonary function improved remarkably. She was commenced on progesterone, which improved her condition even further. This case report retrospectively follows the progression of her disease from the onset of symptoms 5 years before she was referred to us for treatment.
