结肠憩室病的临床特征及多层螺旋CT表现

Clinical features and multislice spiral CT manifestations of colon diverticulosis

目的分析结肠憩室病的临床特征及多层螺旋CT(MSCT)表现。方法12例经肠镜证实为结肠憩室病的患者,均行MSCT检查。总结其临床特征及MSCT影像特点。结果12例结肠憩室病患者均为老年人,主要临床表现为腹痛、腹泻。5例患者的憩室发生于升结肠,4例同时发生于升结肠和横结肠,2例同时发生于横结肠和降结肠,1例发生于全结肠。结肠憩室病MSCT表现为结肠旁多发小圆形囊性病灶,直径为2.0~10.0mm。9例患者的囊袋内容物为粪石,3例为气体。结论结肠憩室病常见于老年人,其MSCT直接征象为结肠旁多发结节形、环形、“C”形高密度影或薄壁小气囊,直径多不超过1cm。

Objective To analyze the clinical features and multislice spiral CT(MSCT) manifestations of colon diverticulosis. Methods Twelve patients enteroscopically diagnosed as colon diverticulosis all underwent MSCT examination. Their clinical and MSCT image features were summarized. Results All of the 12 patients with colon diverticulosis were elderly,and the main clinical manifestations included abdominal pain and diarrhea.The diverticulums of 5 cases, 4 cases,2 cases and 1 case were located in the ascending colon,transverse and ascending colon simultaneously,transverse and descending colon simultaneously,and all segments of colon,respectively.The colon diverticulosis on MSCT manifested small and round multiple cystic lesions beside the colon with a diameter of 2.0-10.0 mm.Bezoar and gas were observed in the sacs of 9 cases and 3 cases,respectively. Conclusion Colon diverticulosis is common in elderly people,and its direct sign of MSCT features is nodular,annular or C-shape multiple high-density lesions or thin-walled air sacs usually with a diameter ≤1 cm.
