A Case of Isolated Hydrosalpinx Torsion in a Young Female: Diagnostic and Surgical Challenges

ABSTRACT: Isolated torsion of a hydrosalpinx is an exceptionally rare gynaecological emergency that often presents with vague and non-specific symptoms, leading to delays in diagnosis. Hydrosalpinx is a known predisposing factor for tubal torsion, yet isolated involvement without ovarian pathology is uncommon. We report the case of a 22-year-old woman presenting with acute right lower abdominal pain and vomiting, in whom ultrasonography demonstrated a cystic adnexal lesion distinct from the ovary. Laparoscopic evaluation confirmed isolated torsion of the right hydrosalpinx with necrosis, necessitating salpingectomy. Early laparoscopic intervention enabled prompt recovery and preservation of ovarian function. This case highlights the importance of maintaining a high index of suspicion for isolated tubal torsion in reproductive-aged women presenting with acute pelvic pain.
