RESUMO
Catamenial hemoptysis is syndrome characterized by bleeding from the bronchial trees and lungs that occurs synchronously with the female menstrual cycle. Etiologic mechanism of pulmonary endometriosis is still controversial, and the diagnosis is usually made on the basis of the clinical history and exclusion of other causes of recurrent hemoptysis. Serial computed tomograms of the chest during and in the interval between menstruations have been proved to be a useful confirmatory test. We experienced a 33-year-old female patient who had been previously diagnosed as pelvic endometriosis pathologically, experienced cyclic hemoptysis during menstruations. The diagnosis of pulmonary endometriosis was made based on her history and changes in the character of the lesions as documented on radiologic studies of the chest. She was treated successfully with GnRH analogue and there is no evidence of recurrence.
