ABSTRACT: Pedunculated fibroid torsion presenting as a case of acute abdomen from sigmoid volvulus and large bowel perforation is rare. Without prompt diagnosis and intervention, this could lead to serious morbidity and mortality. Ms FM was a 52-year-old perimenopusal woman who was admitted to the Intensive Therapy Unit (ITU) with worsening symptoms of confirmed Covid-19 infection. On the 10th day of her admission, she developed abdominal distension and tenderness. A pelvic ultrasound scan showed a large pedunculated fibroid measuring 23 × 15 × 22 cm. The plan was for conservative management to use pain killers. Following deterioration of her clinical state, an abdominal CT scan was done which confirmed a large uterine fibroid, large bowel distention. CT findings also showed sigmoid volvulus and large bowel perforation. Following a multidisciplinary team assessment, she had an emergency exploratory laparotomy with findings of a large, torted, pedunculated fibroid with adherent sigmoid colon which had become twisted and obstructed. The large bowel segment above the Sigmoid volvulus was grossly distended and there was a gangrenous hepatic flexure with perforation. She had a right hemicolectomy, a de-functioning colostomy and subtotal hysterectomy. Postoperatively, she made very good clinical improvement. Fibroid histology report showed tissue infarction and necrosis which confirmed the torsion. She was discharged home after making good recovery.
