Right colon, sigmoid colon, and transverse colon diverticulitis in the same patient: report of a case.

Although sigmoid colon diverticulitis is frequently seen, right colon and transverse colon diverticulitis remain rare forms of the disease. This case report examined the disease course of a 46-year-old female who first presented to our institution in 1990 with perforated right-sided diverticulitis. During the next 11 years, she developed sigmoid colon diverticulitis and then transverse colon diverticulitis. The right and sigmoid colon diverticulitis were treated with surgery and the transverse colon diverticulitis was managed conservatively. This is the first reported case of a single patient who had separate episodes of diverticulitis in the right, transverse, and sigmoid colon. The evaluation and management of this patient has mirrored a trend in the literature and clinical practice.
