Appendicular Diverticulum and Colorectal Neoplasia: A Case Series and Literature Review.

Appendicular diverticulosis is a rare condition often discovered incidentally and associated with an increased risk of complications such as perforation, bleeding, and neoplasia. We present three cases of appendicular diverticulosis with varying presentations: one associated with acute appendicitis and two identified incidentally during surgical procedures. After a thorough literature review to back up this report, 19 cases were found with this condition and similar characteristics: of 19 patients, the majority were aged 40-60 years, with a slight male predominance, and abdominal pain was the most common symptom. The primary diagnostic modality was abdominal computed tomography, with perforation observed in approximately 27% of cases and one instance of appendiceal adenocarcinoma identified. The potential for serious complications underscores the importance of early diagnosis and individualized management to prevent morbidity, given the higher likelihood of neoplasia and perforation in patients with this condition.
