Transverse vaginal septum is a residual vaginal plate composed of the Müllerian duct and urogenital sinus. Imperforate hymen results from failure of perforation of the membrane between the urogenital sinus and vaginal cavity. We report a rare case of concurrence of these two conditions. A 16-year-old girl had been treated with puncture several times for hematometra and hematocolpos from 13 years of age because of monthly occurrence of lower abdominal pain without menstrual bleeding and was referred to our hospital. Magnetic resonance imaging demonstrated hematometra, hematocolpos and expansion of the vaginal fornix. The imperforate hymen was incised and a slight adhesion at the lower vaginal cavity was detached. After that, a complete transverse vaginal septum, which was 5 mm thick, was identified. It was excised after ultrasonography-guided puncture. Although two cycles of menstrual bleeding took place, molimina recurred. Re-operation was performed 6 months after the first operation, and recurrence of adhesion in the lower vaginal cavity was identified. A silicon dilator was inserted, but she could not use it at home and instead used a tampon. Cyclic menstrual bleeding is observed 4 months after the second operation.
Fallopian tube torsion caused by a paraovarian or paratubal cyst during pregnancy is rare. A 30 year old woman (gravida 2, para 1) was referred to our hospital with acute-onset right abdominal pain and a coinciding cyst measuring 5cm detected by ultrasonography at 37 gestational weeks. Although ovarian torsion was suspected, her symptoms were mild, and in consideration of operative difficulty, we decided to postpone laparoscopic management until after delivery. At 38 gestational weeks, she delivered a male infant (2810g) after induction. Her symptoms continued and laparoscopic surgery was performed at 6 days after delivery, which revealed right fallopian tube torsion due to a paraovarian cyst. The right ovary was intact. The right fallopian tube and the paraovarian cyst was necrotized, adhered to the peripheral peritoneum, and was resected laparoscopically with relative ease. Her postoperative course was uneventful.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
