title: Sonographic appearance of an appendiceal diverticulum.
abstract: The increasing use of sonography for evaluating acute abdomen has brought greater recognition of appendicular abnormalities. We present an incidental finding of an appendiceal diverticulum during a sonographic examination of a 4-year-old child with acute appendicitis. Abdominal sonography showed an enlarged, swollen appendix with a diameter of 1.1 cm and a small, fingerlike lateral projection approximately 2.0 cm from its tip. The specimen, resected during an appendectomy, was 5.5 cm long and 1.0 cm in diameter and had a 0.3-cm outpouching. Microscopic examination revealed a pseudodiverticulum composed of mucosa and muscularis mucosa.
