Abstract

ABSTRACT

We present a case of congenital midgut volvulus detected by prenatal sonography and ultrafast magnetic resonance (MR) imaging. At 34 weeks of gestation, enlarged hyperechogenic loops without peristalsis was identified by sonographic examination. On ultrafast T2-weighted single-shot fast-spin echo MR imaging, enlarged loops exhibited a lower signal intensity than the surrounding bowel loops, suggesting intraluminal hemorrhage. At explorative laparotomy following delivery, midgut volvulus causing hemorrhagic necrosis was found. Combined use of sonography and ultrafast MR imaging is useful to identify fetal midgut volvulus with hemorrhagic change.
