Torsion of the fallopian tube in a pre menarcheal 12year old girl: A rare case report
Posted by on Thursday, 7th May 2009
Isolated torsion of the fallopian tube in pre menarcheal girls is very rare. However correct diagnosis and treatment are needed in order to optimize salvage of fallopian tube. While torsion of the adnexa is relatively common, isolated torsion of the fallopian tube alone, first described in 1890(Sutton, 1890) remained a rare occurrence with an incidence of 1 in 1.5million women(Hansen, 1970). It most frequently during menstruating years, but also has been reported in pre and pause menopausal women. It has also been reported in infants and pre menarcheal girls. Many etiologies for tubal torsion have been suggested including hydrosalpinx, tubal carcinoma, prior tubal ligation(Krissi et al 1997), ovarian and paraovarian masses, pregnancy, hydatid of Morgagni and peristaltic abnormalities. The condition may also occur in pregnancy, labour and pre menstrual period.Diagnosis of this condition is often delayed because of the rarity of its occurrence and prolonged investigations to rule out more common causes of acute abdominal pain.
Case Report:
13year old Miss. X, who has not attained menarche, was referred to our centre with history of lower abdominal pain of two days duration and with an ultrasound scan report showing right ovarian cyst of 5x3cm, for diagnostic laparoscopy. She has no significant past medical and surgical illnesses. She has not attained menarche. On examination there was no pallor, vital signs were stable, has normal secondary sexual characters, systemic examination was normal. Abdominal examination revealed no palpable mass or tenderness. Transabdominal scan showed uterus to be 3.5x2.2cm, endometrium 3mm, right adnexal mass of 4.5x4cm seen, which is anechoic with fine basal echoes. Left ovary was not seen. Ultrasonic diagnosis of right ovarian cyst was made and laparoscopy was decided. At laparoscopy the peritoneum, appendix, pouch of Douglas and upper abdomen were normal. Uterus was normal looking, both ovaries normal. Right tube was twisted thrice along with a paratubal cyst of 4cm. The cystic mass appeared bluish. Untwisting of the right tube , right paratubal cystectomy done, edges reformed. Intraoperative and post operative period were uneventful. The patient was discharged was discharged the next day. HPE diagnosis was consistent with paratubal cyst(twisted).
Conclusion:
Isolated fallopian tube torsion is rare entity especially in pre menarcheal age. At first episode of torsion of fallopian tube, tubal preservation must be the rule unless the tube is totally necrotic. A timely diagnosis and surgical intervention may allow preservation of the tube.
