RESUMO
BACKGROUND: Though paratubal and paraovarian cysts are rare in adolescent females, the influence of post-menarchal hormonal stimulation on these tubal derivates can produce large and clinically significant adnexal pathology. Ovarian torsion secondary to paratubal cysts is rare due to the cyst's location and ipsilateral recurrence is uncommon. CASE: We report a case of an 11-year-old female with a large right paratubal cyst causing ovarian torsion on two separate occasions within one year and our approach to surgical management. CONCLUSION: Excision of a paratubal or paraovarian cyst that causes ovarian torsion is necessary to decrease the risk of cyst recurrence and ovarian torsion in the future. Timely diagnosis and treatment of ovarian torsion enables preservation of ovarian function and patient fertility.
