Prenatal three-dimensional sonographic findings associated with fetal defecation. Case Report.

Routine ultrasonography examination may miss fetal defecation and if seen it can be a source of misinterpretation which can lead to a wrong diagnose and management of pregnancy. We report two rare cases of fetal defecation in the second trimester and we describe 3D sonographic findings associated with this condition.

Sigmoidal polyp with adenocarcinoma discovered by transvaginal three-dimensional ultrasonographic virtual colonoscopy.

Adenocarcinoma of the colon represents the third most frequent cause of death from cancer, being surpassed only by lung and stomach cancer. Early screening and diagnosis of polyps are important for a good prognosis. Based on a clinical case, a novel approach is presented for screening of sigmoidal polyps and neoplasia using transvaginal 2D, 3D mode in women. This novel and simple technique can be used to visualize the sigmoid diverticula during routine gynecological examination via 3D transvaginal ultrasound probe.
