A case of pulmonary endometriosis presenting with catamenial pneumothorax / 대한산부인과학회지

ABSTRACT

Endometriosis is a relatively common gynecologic disease. However thoracic endometriosis syndrome is exceedingly rare among various types of external endometriosis. We experienced a case of 35-year-old woman who presented with recurrent episodes of spontaneous right-sided pneumothorax that occurred during her menstrual periods. After the localization of the disease site by means of chest radiography and computed tomography of the thorax, a chest tube was inserted after which bullectomy and pleurodesis using doxycycline were performed. A hormonal treatment with gonadotropin-releasing hormone (GnRH) agonist for 12-months was also conducted. However, right-sided pneumothorax recurred two times after these procedures. Subsequently, surgical excision of diaphragmatic lesion along with pleurodesis was underwent. To prevent recurrence, we maintained long-term GnRH agonist administration with add back therapy using low dose estrogen-progesterone. Menstruation stopped, and the chest pain disappeared. During a 19-months follow-up period, pneumothorax did not recur. We report this case with a brief review of the concerned literatures.
