Pulmonary lymphangiomyomatosis causing bilateral pneumothorax during pregnancy.

A 32-year-old woman, 12 weeks pregnant, presented with bilateral spontaneous pneumothorax that did not heal with tube thoracostomy. At right and left thoracotomy, lymphangiomyomatosis of the lung was found and treated by pleurodesis. Lymphangiomyomatosis has been infrequently reported in the surgical literature, even though it may befall the thoracic surgeon to establish the diagnosis and aid in treatment.
