To illustrate cases of midgut volvulus in 7 children, of whom only 2 were neonates, diagnosed initially by sonography using the whirlpool sign, and to emphasize the importance of considering malrotation and midgut volvulus in the differential diagnosis of acute or chronic abdominal pain in those beyond the neonatal period, the usual time of presentation for midgut volvulus. ⋯ The sonographic whirlpool sign is a valid and highly sensitive sign for the diagnosis of midgut volvulus secondary to malrotation, and sonographers should be aware that it frequently occurs beyond the neonatal period with symptoms other than bilious emesis.
