A Rare Case of Malrotation and Midgut Volvulus with Whirlpool Sign.

We report a rare case of midgut malrotation and volvulus with "whirlpool sign" in a new-born infant. The "whirlpool sign" is an imaging characteristic of midgut volvulus and has a high predicting value for volvulus. Malrotation or malrotation with volvulus can be effectively diagnosed based on these characteristics. Ultrasound diagnosis has the advantage of no radiation exposure. Color Doppler documenting the reversal or aberrant superior mesenteric vein/superior mesenteric artery axis is not only predictive but also diagnostic of malrotation of gut. The rapid and accurate diagnosis of volvulus by ultrasound helps to establish the diagnosis of malrotation in time and thus allows for urgent surgical intervention to avoid bowel necrosis.
