Broad ligament fibroid mimicking as ovarian tumor on ultrasonography and computed tomography scan.

Giant fibroids are known to arise from the uterus, and very rarely from the broad ligament. Large fibroids often undergo hyaline, cystic, and at times, red degeneration. In the present case, cystic degeneration with intervening septations in an adnexal mass raised the suspicion of ovarian neoplasm as the ovaries were not seen as separate from the lesion. The ultrasonographic and contrast-enhanced computed tomographic findings of this case were characteristic of ovarian neoplasm. The differential diagnosis included rare possibility of giant fibroid with cystic degeneration. The diagnosis was confirmed on histopathological examination. The patient underwent excision of the broad ligament fibroid, hysterectomy, and bilateral salpingo-oophorectomy. Magnetic resonance imaging has a role in the diagnosis of such lesions.
