Abstract
BACKGROUND: Isolated fimbrial torsion is a rare gynecological emergency that can lead to severe complications if not promptly diagnosed. Its clinical presentation often mimics more common causes of abdominal pain, creating a significant diagnostic challenge. CASE PRESENTATION: This case report describes a 47-yr-old woman presenting with right lower quadrant abdominal pain. The initial clinical and ultrasound findings were suggestive of acute appendicitis. However, diagnostic laparoscopy revealed isolated gangrenous torsion of the right fallopian tube fimbria. CONCLUSION: This case underscores the importance of including fimbrial torsion in the differential diagnosis of right lower quadrant pain in women, even when clinical signs suggest a more common etiology. A comprehensive intraoperative evaluation is crucial when initial findings do not fully explain the clinical presentation, ensuring timely intervention and prevention of long-term complications.
