A 51-year-old woman visited our institution with a chief complaint of abdominal pain. Blood laboratory testing revealed a carcinoembryonic antigen level of 13.4 ng/mL. Magnetic resonance imaging revealed a massive pelvic mass with marked wall thickening, partly accompanied by a high-signal-intensity cystic component in T2-weighted images. The entire tumor had low-signal intensity in T1-weighted images. We diagnosed a ruptured ovarian tumor, and the patient underwent emergent laparoscopic left salpingo-oophorectomy. Pathological examination revealed metastatic colon cancer to the ovary, and lower gastrointestinal endoscopy confirmed sigmoid colon carcinoma. Laparoscopic sigmoidectomy was performed followed by adjuvant chemotherapy with capecitabine + oxaliplatin. Ruptured metastatic ovarian tumor is extremely rare. With early diagnosis and laparoscopic resection, the primary lesion can be identified and treated quickly.
