Introduction: Leiomyoma is the most common tumour of the uterus. Broad ligament is the most common extrauterine site for occurrence of leiomyoma. These benign tumours in the broad ligament are usually asymptomatic but if neglected can reach to enormous size and result in chronic pelvic pain, compression of bladder, and bowel with dysfunction. Case Report: We are presenting a rare case of leiomyoma of broad ligament in a post- menopausal 45-year-old female with complaints of pain and heaviness in lower abdomen. On clinical examination, there was a 26-weeks size firm, non-tender, mobile mass extending to the umbilicus. Ultrasound pelvis showed grossly enlarged uterus with multiple fibroids in anterior and posterior myometrium, largest one seen arising from posterior myometrium. Bilateral ovaries not visualised. CT scan showed intramural uterine fibroid of about 3.4x2.6 cm in posterior uterine wall with a soft tissue mass lesion of about 20.6x18.5x9.5cm in left adnexal region extending to umbilicus possibly ovarian fibroma. Result: Enucleation of broad ligament fibroid was done along with TAH BSO. Histopathology confirmed it to be a soft tissue tumour-leiomyoma. Conclusion: Broad ligament leiomyomas mimic ovarian tumours on clinical and radiological examination and there may be difficulties in differentiating the two. Thus, histopathology plays an important role to confirm the diagnosis. Clinical Significance: We present this case because of its rarity and diagnostic difficulties it posed.
