title: Roentgenographic findings in work hypertrophy of the muscularis propria of the terminal ileum.
abstract: This case is presented as an uncommon example of valvulae thickening caused in part by work hypertrophy of the circular muscular layer. This normal response of smooth muscle may occur in association with progressively obstructing lesions of the colon or ileocecal valve. Recognition of a similar abnormal small-bowel appearance may suggest the presence of a more distal obstructing lesion.
