Inflammation of the ileium is ILEITIS. There are three kinds:
distal, regional, and terminal.
Regional enteritis is a subacute chronic enteritis, of unknown
cause, involving the terminal ileum and less frequently other parts
of the gastrointestinal tract; characterized by patchy deep ulcers
that may cause fistulas, and narrowing and thickening of the bowel
by fibrosis and lymphocytic infiltration, with noncaseating
tuberculoid granulomas that also may be found in regional lymph
nodes; symptoms include fever, diarrhea, cramping abdominal pain,
and weight loss. Syn: Crohn disease, chronic cicatrizing enteritis,
granulomatous enteritis, distal ileitis.
