The paper reports a case of a 35-year-old woman with catamenial hemoptysis, attributed to thoracic endometriosis localized to the right upper lobe posterior segment and the right lower lobe superior segment, identified on chest CT during menstruation. The authors note that diagnosis is usually made on clinical grounds and by exclusion of other causes, while the pathogenesis of thoracic endometriosis remains uncertain with several proposed mechanisms (e.g., retrograde flow, microembolization, and differentiation hypotheses). Treatment consisted of effective bisegmental wedge resection for the localized pulmonary lesions. This paper is centrally about endometriosis — it describes pulmonary parenchymal (thoracic) endometriosis causing catamenial hemoptysis.

Abstract

Catamenial hemoptysis is a term used to describe recurrent hemoptysis occuring at the time of menstruation and is caused by the presence of thoracic endometriosis. The diagnosis is almost always established on the clinical grounds and by exclusion of other causes of recurrent hemoptysis. The pathogenesis of the thoracic endometriosis is not clear but several hypothesis have been proposed, such as retrograde flow of the endometrial tissue through the diaphragmatic defects, microembolization through pelvic veins and differenciation into endometrial tissues. We report a case of a 35-year-old woman who presented with catamenial hemoptysis caused by the endometriosis of lung parenchyme. The lesion was localized to the right upper lobe posterior segment and right lower lobe superior segment by the computerized tomogram of the chest during the time of mensturation and treated effectively with bisegmental wedge resection.
