Appendicular pseudodiverticula and acute appendicitis: Our 12-year experience

“…Their incidence is estimated as 0.77% in appendectomy specimens, and 0.66% in necropsy specimens, versus true diverticula, which only develop in 0.014% of surgical specimens and represent 1 to 6.6% of appendicular diverticulosis (5)(6)(7)8).…”

“…Most common complications such as perforation and inflammation cause abdominal pain that mimics acute appendicitis. Insidious, intermittent, prolonged pain usually in the absence of nausea, vomiting or anorexia, and more common in males in their forties, are characteristics considered to be differential from acute appendicitis by some authors (1,(5)(6)(7)8,13).…”

“…They have also been described as incidental radiographic findings (barium enema, ultrasounds, computerized tomography) and as findings during laparotomy (1,3,5,7,8,(10)(11)(12)14,(16)(17)(18)(19)(20)(21). In our series preoperative imaging techniques did not contribute to definitive diagnoses.…”

Appendiceal diverticulitis, a rare relevant pathology: Presentation of a case report and review of the literature

“…Kallenback et al [20] demonstrated a similar association between appendiceal diverticula and neoplasms (43.6%; 17 cases on a series of 39 patients) while Marcacuzco et al had a lower incidence (7.1%; 3 cases on a series of 42 patients) [21]. It is recommended to execute an accurate evaluation of the appendiceal specimen when diverticula are evidenced in order to exclude possible concomitant neoplastic disease [18], [22], [23], [24].…”

“…A correct diagnosis is important not only because of the higher complication risk but also for the higher risk of associated appendiceal neoplasms, especially carcinoid tumors and mucinous adenomas [3], [18], [19]. Dupre et al reported 11 cases of neoplasia on a series of 23 patients with appendiceal diverticula (47.8% of total).…”
