Isolated fallopian tube torsion is rare and often difficult to diagnose. This case report describes a post pubertal, sexually non active teenage girl presenting with acute onset of pelvic pain. Physical examination revealed significant right adnexal tenderness. Transabdominal ultrasound identified a normal right ovary was bulky measuring 4x 5 cm with a separate 1.5x 4 cm cystic tubular structure adjacent to it. Laparoscopic finding of an isolated necrotic tubal torsion was identified. Isolated torsion of a fallopian tube should be considered in the differential diagnosis of lower abdominal pain in any female of reproductive age. Low threshold for laparoscopic assessment of the pelvis can provide early diagnosis as well as treatment. It should therefore be encouraged especially in women of reproductive-age group, as early diagnosis and management can help salvage the affected tube and ovary and preserve or maximize their future fertility.
