Abstract ISSN: 2573-1017 Diverticulosis of the appendix is a very rare entity that clinically presents OPEN ACCESS similar to acute or chronic appendicitis. Diagnosis is almost always made at time of appendectomy or on pathology. INTRODUCTION It was first described by Kelynack in 1873 and classifies it as acquired and congenital. Acquired is rare cause of acute appendicitis with a range of 0.004% to 2.1% [1]. Congenital is even rarer with few case reports presented and an incidence of 0.014% [1]. Treatment of appendiceal diverticulitis and diverticula are the same as appendicitis, but must be done more urgently as there is an associated with perforation and neoplasm. The neoplasms usually seen are carcinoid and mucinous adenomas.PRESENTATION We now present OF CASE a case from our Community Hosptial. We present the case of a healthy 30 year old female admitted with a two day history of abdominal pain. The pain gradually shifted to the right lower quadrant, with no other associated Figure 1 symptoms. Her physical exam was typical for acute appendicitis. Cross section of the specimen showing 2 diverticula. She had no leukocytosis, however she had radiographic findings consistent with early acute appendicitis. She underwent a Laparoscopic Appendectomy; the tip of her appendix was enlarged and inflamed while the base was found to be mildly hyperemic. The patient had an uneventful recovery. Upon histologic evaluation, her appendix had Goblet cell hyperplasia in two large diverticuli at the distal aspect with polymorphonuclear infiltration (Figure 2) suggestive of acute appendiceal diverticulitis.DISCUSSION No occult neoplasm was demonstrated (Figure 1). Appendiceal diverticulitis is mainly diagnosed during surgery or on pathology, but rarely on preoperative imaging. In review of Figure 2 the literature Abdullgaffer, Sohn, and Collins reporting 0.014%, Polymorphonuclear infiltration. 3.7%, and 1.4% respectfully [4,12,13]. Histologically 2 types are recognized: acquired and congenital. Acquired diverticuli are usually seen at the distal end of the appendix. They are usually Diverticuli can be seen with ultrasound, but is highly range from 2-5 mm and described as pseudo diverticuli, as they dependent on the sonographer’s skill.

A herniation of all three layers is seen in the to locate, unless they are unusually large. congenital form, which is located on the antimesenteric edge of the appendix. Our patient’s appendix was pseudo diverticuli thus While it clinically mimics acute appendicitis, it is associated being classified as acquired diverticuli [14]. with an increased incidence of appendiceal neoplasms and a Cite this article: Joel C, Noubar K (2017) Diverticulitis of the Appendix: Rare but Real.
