view case

• Diverticula of the colon are usually acquired deformation and are found most frequently in western urban civilizations.
• Diverticula are usually multiple; their most common location is the sigmoid and left colon.
• Acute diverticulitis and spastic diverticulosis may both be associated with a classic triad of presentation: left lower-quadrant pain, fever, and leukocytosis.
• Localized abcess formation occurs more commonly than peritonitis. Fistula formation, with communication to the bladder, vagina, skin, or other bowel loops, is present in the minority of cases.
