RESUMO
@#Isolated fallopian tube torsion is a rare but significant gynecological cause of lower abdominal pain in adolescent females with or without risk factors. A 12-year-old female was initially treated as urinary tract infection, acute appendicitis, and a possible ovarian pathology. Intraoperatively, it was isolated fallopian tube torsion. The entity is difficult to recognize preoperatively because of its vague clinical presentation and lack of specific laboratory and imaging findings, and diagnosis is done ultimately during surgery. Isolated tubal torsion should be considered in cases of acute lower abdominal pain since awareness and early detection of the condition, especially in children and adolescents, allows early surgical intervention that may render preservation of the tubes.
