Chronic intussusception in childhood

Abstract.

A rare case of chronic intussusception is reported. Radiological investigation including ultrasound, CT and barium enema provided the correct diagnosis. Ultrasound revealed a solid mass near the transverse colon in the right lower abdomen. CT demonstrated the real nature of the solid mass as being the classical ’coiled spring' of intussusception. The barium enema was unsuccessful as an attempt at hydrostatic reduction, but confirmed the diagnosis by a ’crescent-shaped' filling defect in the ascending colon. The patient was discharged after an uneventful surgery and recovery. No organic lesion that precipitated the chronic intussusception was discovered at operation. Radiological findings, the typical clinical picture and adequate treatment are discussed.
