Mucinous ovarian cystadenoma is a benign tumor, which accounts for 15% of all ovarian tumors and, when diagnosed, 80% are benign, 10% limitrophe and 10% malignant. It is a cyst that arises from the ovary surface epithelium, presenting multilocular feature with plain surface. It is more common between 30- and 50-years old persons and clinical signs differ from other ovarian pathologies because they present rapid growth, reach large dimensions and evolve with peritoneal pseudomyxoma, causing a significant increase in abdominal volume. Imaging methods such as ultrasonography and computed tomography, as well as the tumor markers CA-125 and CEA, are fundamental for its elucidation and therapeutic planning. We report a case of giant mucinous cystadenoma of the left ovary in a 61-year-old patient admitted to the emergency room.
