Inflammatory Intestinal DiseasesSlide2
Ulcerative Colitis
Unknown etiology
Mucosal inflammation
and ulceration
in the large intestine
Always involves the rectum
Early; Widespread fuzzy, serrated ulcerations
Late; Rigid tube appearance, ‘lead pipe’
Complications; Toxic
megacolon
, carcinomaSlide3
Ulcerative Colitis
Fine serrated margins
Represents mucosal ulcerationsSlide4
Ulcerative Colitis
Close up serrationsSlide5
Ulcerative Colitis
Diffuse involvement with ulcerationsSlide6
Ulcerative Colitis
Extensive descending colon
involvment
with deep ulcerations of mucosa.Slide7
Ulcerative Colitis
Fine serrations in the sigmoid colon.Slide8
Ulcerative Colitis
AP film from air contrast barium enema
Acute disease
Smooth surface distal colon and rectum or fine serrations
Loss of
haustra
Some narrowingSlide9
Ulcerative Colitis Chronic
Areas of marked narrowing
Shortening of the colon
Abnormal smoothness
No
haustrationsSlide10
Crohn’s Disease
Unknown etiology
Transmural process
Any part of alimentary tract
Mostly terminal ileum, proximal colon, may affect the duodenumSlide11
Crohn’s Disease
Cobblestone appearance (edema with criss-crossed ulcers)
Skip areas of normal bowel
Complications- obstruction,
fistulas
and abscessSlide12
Regional Enteritis
Separation of loops
Skip areas of more normal appearing small intestine
Areas of edematous small intestine
Areas of narrowingSlide13
Regional Enteritis
Marked narrowing of the terminal ileumSlide14
Crohn’s Disease
Spot films of terminal ileum
Areas of narrowing separated by areas of more normal bowel
Separation of loops
Fistulas (arrow)
