ABSTRACT
The commonest diagnosis of a cystic mass in the pelvis is ovarian cyst, here we report a case of cystic degeneration of broad ligament fibroid mimicking as a ovarian cyst. A 45-year-old lady presented with abdominal discomfort. On evaluation, a pelvic mass of 20 weeks size of varying consistency was noted. Ultra sonogram and Magnetic Resonance Imaging gave a differential diagnosis of right sided broad ligament fibroid and ovarian cyst. Anticipating possible ovarian mass owing to its size, laparotomy was performed and noted a large false broad ligament fibroid which has undergone cystic degeneration. Total abdominal hysterectomy and bilateral salpingo-oopherectomy was performed, however a differential diagnosis of ovarian mass should always be made before surgery.
