Overview

Diverticulitis is the inflammation of the diverticulum which is a herniation of the mucosa and submucosa of the colonic wall that may fill with fecal material or undigested food particles. 
Abdominal pain is usually localized, abrupt, steady and may worsen over time; other signs and symptoms are fever, anorexia, nausea without vomiting, and altered bowel movements, commonly constipation but may also present with diarrhea or tenesmus.
Selective imaging is recommended in patients with a previous history of acute diverticulitis, absence of vomiting, pain localized to the left lower quadrant and/or a C-reactive protein (CRP) level of >50 mg/L .
The management of diverticulitis depends on the clinical presentation, severity of inflammation, location of the lesion and presence of concomitant diseases.
