Retrograde prolapse of the lleocecal valve

Retrograde prolapse of the ileocecal valve results when redundant mucosa produces prominent lips of the ileocecal valve. The prominent valve produces a filling defect within the cecum. With manual palpation or hydrostatic pressure of the barium column, this prominent ileocecal valve then prolapses in a retrograde fashion to produce a tapered defect of the terminal ileum. The pliable changing nature of this lesion is characteristic of a benign condition, and this combination of radiographic findings is pathognomonic of this normal variant. Two cases are reported with documentation by surgery and colonoscopy..
