Thoracic Endometriosis Presenting As Recurrent Spontaneous Pneumothorax In A 53-Year-Old Female

A 53-year-old asymptomatic female presented with a third episode of spontaneous pneumothorax in right hemithorax. Previous studies did not demonstrate the etiology of this disease but only sub-pleural bullae. We found typical thoracic endometriosis lesions through video thoracoscopy. After surgical correction and anti-estrogenic treatment, the patient remains asymptomatic. This case is relevant due its presentation, diaphragmatic involvement and the age of the patient.
