A case report of body stalk anomaly complicating a twin pregnancy.

The body stalk anomaly is described as a maldevelopment during embryonic folding in the third week after conception, resulting in a severe defect of the fetal abdominal wall. The extra-embryonic coelom fails to obliterate and parts of the fetal body remain in an exo-coelomic situation. Reports on its occurrence in multiple pregnancies have in the past focused on concordance between monozygotic twins.

MRI of the pelvic ring joints postpartum: normal and pathological findings.

Purpose: To assess the joints of the pelvic ring postpartum and to discern normal postpartum findings and pathologic lesions using MRI.

Materials And Methods: MR images were obtained in six women with severe pelvic ring pain after delivery, in 13 women after uncomplicated vaginal delivery, and in 11 healthy, nulliparous non-pregnant volunteers. Distances of the pubic gap, signal intensities of the pubic cartilage, and signal changes of the pelvic ring bones were determined and evaluated.
