Gangrenous Hydrosalpinx with Isolated Fallopian Tube Torsion in Premenarchal Child.

Hydrosalpinx induced torsion of the adnexa in a premenarchal child without sexual experience is a rare situation and immediate intervention is necessary. This report describes a 10-year old premenarchal female without a history of sexual intercourse who presented with left lower abdominal pain. Ultrasound imaging revealed a left adnexa with thick-walled cystic lesion measuring 5.1 × 3.7 × 2.7 cm suggestive of hydrosalpinx or para ovarian cyst. Diagnostic laparoscopic surgery showed ischaemic tubular shaped cystic left hydrosalpinx that was twisted along its own axis at the level of isthmus. Laparoscopic left salpingectomy was performed within 24 h of presentation leaving behind a healthy left ovary. Early diagnosis is important in preventing further complications including severe infection and peritonitis and to prevent complications that might affect fertility.
