title: Torsion of the fallopian tube in an adolescent female: a case report.
abstract: BACKGROUND
  Torsion of the fallopian tube is an infrequent but significant cause of acute lower abdominal pain in adolescent females that is difficult to recognize preoperatively, although prompt diagnosis and timely surgical treatment are vital to salvage the oviduct.
  
  
  METHODS
  A 17-yr-old virgin presented with sudden and severe right-sided lower abdominal pain with guarding and tenderness, fever, nausea, and vomiting at mid-cycle. Ultrasound scan showed a right ovarian cyst measuring 3 cm in diameter and a normal appendix. There was no leucocytosis. Presumptive diagnosis was a cystic ovarian follicle with ovulatory pain. Her condition improved but did not resolve with supportive treatment. At laparotomy, the right fallopian tube was twisted completely, distended with blood, and necrotic, with a small fimbrial cyst. The left tube, ovaries, appendix, and uterus were normal. Right salpingectomy was performed. Histologic examination revealed diffuse hemorrhagic infarction of the tube and a cyst of the hydatid of Morgagni. She remains well at follow-up.
  
  
  CONCLUSIONS
  Unless a high index of suspicion is maintained for torsion of the fallopian tube in adolescent females, this disorder may not be detected until after tubal destruction.
