Isolated fallopian tube torsion with preservation of ipsilateral ovary. A case report.

Isolated fallopian tube torsion (IFTT) is a rare cause of acute lower abdominal pain in women. Its nonspecific clinical presentation makes preoperative diagnosis more challenging. Laparoscopy is the gold standard in diagnosis and treatment. This is a case of a 25-year-old newly married patient presented to the emergency department with sever acute lower abdominal pain associated with nausea. Clinical physical examination revealed abdominal tenderness. Ultrasound showed a right ovarian cyst measuring 4.5 cm × 4.1 cm with mural nodule, no internal vascularity on color doppler. Laparoscopy was performed where the right fallopian tube was found edematous, darkened red in color. Therefore, isolated fallopian tube torsion was diagnosed and right salpingectomy was performed with preservation of the right ovary. Postoperative recovery was uneventful. Histopathological examination confirmed necrosis of the excised fallopian tube. Isolated fallopian tube torsion is a rare yet noteworthy event. Early diagnosis and timely management are crucial for tubal sparing surgery.
