Ectopic pregnancy in an undescended fallopian tube: a diagnostic challenge.

Uterine malformations are the most frequent anomalies of the Müllerian ducts, but undescended ovaries and fallopian tubes are very rare congenital defects. Pregnancy in these misplaced organs may occur, frequently posing a diagnostic challenge. A case of a ruptured ectopic pregnancy in an undescended fallopian tube associated with other genital malformations is presented.

Feasibility and reproducibility of transvaginal, transabdominal, and 3D volume reconstruction sonography for measurement of the corpus callosum at different gestational ages.

Objective: To compare the feasibility and reproducibility of transvaginal and transabdominal approaches, and 3D volume reconstruction sonography for measurement of corpus callosum (CC) length at different gestational ages.

Methods: Forty-six normal fetuses were examined by 2D and 3D ultrasound at 23-25, 27-28 and 31-32 weeks of gestation. Direct mid-sagittal views were obtained by either a transabdominal and/or transvaginal approach.
