A Rare Case of Broad Ligament Fibroid: A Case Report

Abstract

Ab s t r Ac t Background: The broad ligament is the commonest extrauterine site for occurrence of leiomyoma. Because of its rarity, it poses both clinical and radiological difficulties in differentiating against an ovarian tumor. Case description: We are presenting a rare case of leiomyoma of broad ligament in a 45-year-old female with complaints of lower abdominal lump, pain, and menstrual abnormality. On clinical examination, there was a 18-week-old firm, nontender, and mobile mass extending to the umbilicus. Ultrasound pelvis showed a large hypoechoic lesion of 17 cm × 11 cm × 10.3 cm with internal vascularity in pelvis predominantly on the left side. MRI pelvis showed similar findings. IVP was normal. Result: Laparotomy showed a huge false left-sided broad ligament leiomyoma measuring 17 × 15 cm. Histopathology confirmed it to be a soft tissue tumor-leiomyoma. Conclusion: Broad ligament leiomyomas mimic ovarian tumors on clinical and radiological examination and may pose difficulties in differentiating both. Its diagnosis is difficult on clinical and radiological features owing to its unusual presentation. Thus histopathology plays an important role in confirming its diagnosis. Clinical significance: We present this case because of its rarity and the diagnostic difficulties it posed.
