Catamenial hemoptysis: A case report of pulmonary endometriosis.

We report a case of a patient diagnosed with pulmonary endometriosis and successfully treated with a GnRH agonist. This 34-year-old mother presented cyclic hemoptysis since 4-month. A non-enhanced computed tomography made at the end of the luteal phase revealed a solitary lung nodule with no other abnormalities. A contrast enhanced computed tomography conducted during menses revealed a ground glass opacity extending from the nodule towards hilum. The diagnosis of pulmonary endometriosis was established taking into account the clinical presentation and the imaging findings. Medical treatment by Triptorelin pamoate (Decapeptyl LP® 3 mg Ipsen Pharma, France), a GnRH agonist, was proposed for a period of 6 months. A CT scan performed 3 months after the end of the treatment shows a complete disappearance of the endometriosis nodular lesion.
