Segmental obstructing acute jejunitis in a child.

Acute localized enteritis is a disease of the terminal ileum in adults and children. We have observed acute enteritis confined to the jejunum in a 3 1/2 year-old girl presenting with partial upper intestinal obstruction. Surgical biopsy of the involved region of jejunum revealed acute inflammatory changes in the mucosa and severe edema of the submucosa. Resection of the edematous segment was followed by prompt and apparently permanent recovery.
