Abstract
BACKGROUND: Catamenial pneumothorax is a rare but serious condition for women of reproductive age. We describe a trial of dienogest as hormonal therapy for catamenial pneumothorax and review the literature on hormonal suppressive therapy for this condition. CASE: A 39-year-old female, gravida 0 para 0, presented with recurrent pneumothoraces coinciding with her menses. After surgical therapy, she was started on leuprolide acetate injections for 6 months to reduce recurrence. To reduce long-term side effects of leuprolide acetate, the patient was started on dienogest 4 mg orally once daily instead of leuprolide acetate for hormonal suppression and experienced resolution of recurrent pneumothoraces. CONCLUSION: For women with recurrent catamenial pneumothorax, dienogest may be an effective hormonal treatment option and alternative to long-term GnRH agonist therapy for long-term suppression.
