A rare case of malignant Brenner tumour of ovary manifesting with intestinal perforation due to colonic infiltration is elaborated in the present report. Brenner’s tumour accounts for 1%–2% of all ovarian neoplasms and malignant Brenner tumour is even rarer and only about 5% of Brenner tumours are malignant. A 62-year-old woman came to surgical emergency with 1-month history of abdominal pain, vomiting and constipation with a palpable mass in right iliac fossa. Abdominal radiograph was suggestive of colonic obstruction. Contrast-enhanced CT of the abdomen revealed cystic right ovarian mass of 10.2×8.8 cm2 with pneumoperitoneum. Exploratory laparotomy was done, which revealed mass arising from right ovary involving terminal ileum, cecum and ascending colon. Possibility of ovarian malignancy was kept. Patient underwent debulking surgery along with ileostomy and descending colon mucous fistula was created. Histology was compatible with malignant Brenner tumour of the ovary.
