Isolated Tubal Torsion in the Absence of Ovarian Pathology: A Case Report and Literature Review.

Background: Isolated fallopian tube torsion (IFTT) is an uncommon but important cause of acute lower abdominal pain, particularly in premenarchal girls. Its nonspecific clinical presentation and inconclusive imaging findings often lead to delayed or incorrect diagnosis.

Case presentation: We report the case of a 13-year-old premenarchal girl who presented with right iliac fossa pain and was initially found to have a para-ovarian mass on ultrasonography. Her symptoms temporarily subsided with conservative management; however, she re-presented with worsening pain. Diagnostic laparoscopy revealed torsion of the right fallopian tube associated with a hemorrhagic para-tubal cyst. A right salpingectomy was performed due to irreversible ischemic changes of the tube.

Conclusion: This case highlights the challenges of diagnosing IFTT in young females. It aims to increase awareness among clinicians as early surgical intervention can preserve tubal function and prevent complications.
