EP25.10: Intestine tumour presenting as an adnexal mass

Ovarian cancer is the fifth more common type of cancer in women and the forth cause of cancer death in women. Gynecological ultrasound is one of the main investigation methods that allows the identification and detailed description of pelvic adnexal masses at first, because of its potential in reconstructing highly definitive images and its simple application, although it is an extremely operator dependent technique. A 67 year old woman was referred to our gynecological consultation because of lower abdominal pain and a suspected right ovarian cancer. By transvaginal ultrasound and Colour Doppler imaging a solid mass in the retrouterine area was found, dimension of 78x44x40mm, adherent to the posterior face of the uterus and to the right ovarium. Part of the mass, 4 cm diameter, was seen to be intensely vascularised; the remaining part wasn't and it was suspected to be a fecaloma. It was evaluated through the IOTA international scale. The ultrasound examination showed a positive sliding sign. The vascularised mass was indeed suspected to be originating from the lower part of the bowel, the inner layer of the sigma. The mass had been surgically resected, as well as the anterior part of the rectum and the uterus with the adnexals on both sides. The diagnosis was of lower bowel Adenocarcinoma, poorly differentiated, G3, and ulcerate.
