A curious case of colitis
Segmental colitis associated with diverticulosis (SCAD) is a rare variant of chronic colitis that is limited to segments of the left colon that harbor diverticula. Histologically, SCAD is known to mimic chronic idiopathic inflammatory bowel disease. Patients usually present with hematochezia and cramping abdominal pain; SCAD often resolves spontaneously without treatment, or completely after a limited course of therapy. Due to the histologic overlap with ulcerative colitis and occasional Crohn colitis, the implications of an inaccurate diagnosis are significant.
