OBJECTIVE
To describe the computed tomographic findings of appendiceal diverticulitis.
METHODS
Computed tomography (n = 20) and clinical findings in 23 patients with appendiceal diverticulitis were retrospectively reviewed and compared with those in 23 patients with usual acute appendicitis.
RESULTS
Computed tomography visualized the inflamed diverticula (up to 4 per patient) mostly as small (median, 7.5 mm) round cystic outpouchings at the distal appendix with contrast enhancement at the cyst wall in 16 (80%) patients with appendiceal diverticulitis. In 50% of appendiceal diverticulitis patients, computed tomographic diagnosis of accompanying appendicitis was false positive. Appendicolith was rarely observed in the appendiceal diverticulitis group (5% vs 48%, P = 0.002). No significant difference was observed in the clinical findings except for the patient age (median, 45 vs 31 years; P = 0.001).
CONCLUSIONS
Most appendiceal diverticulitis can be differentiated from usual acute appendicitis at computed tomography by visualization of the inflamed diverticulum.
目的
描述阑尾憩室炎的计算机断层扫描表现。
方法
回顾性分析23例阑尾憩室炎患者的计算机断层扫描结果（n = 20）及临床表现，并与23例普通急性阑尾炎患者的结果进行比较。
结果
在23例阑尾憩室炎患者中，计算机断层扫描显示发炎的憩室（每位患者最多4个）大多为阑尾远端的小圆形囊性袋状突出（中位值7.5 mm），16例（80%）患者的囊壁有对比增强。在50%的阑尾憩室炎患者中，计算机断层扫描对合并阑尾炎的诊断为假阳性。阑尾憩室炎组很少观察到阑尾结石（5%对48%，P = 0.002）。除患者年龄外（中位值45岁对31岁；P = 0.001），临床表现无显著差异。
结论
通过观察发炎的憩室，大多数阑尾憩室炎在计算机断层扫描中可与普通急性阑尾炎相鉴别。
