Abdominal CT of 230 patients (310 CT examinations) with a diagnosis of malignant melanoma was retrospectively reviewed for the evaluation of small bowel and mesenteric involvement. Seventeen (7.4%) patients had evidence of small bowel and mesenteric involvement on CT. There were four distinct patterns of disease: (a) intraluminal masses in 3 patients; (b) ulcerating lesions in 2; (c) diffuse infiltration in 6; (d) implants in 10. Four patients had more than two patterns of involvement. Of the 10 patients with tumor implants, carcinomatosis was noted in 2. Two patients had intussusception and 4 had extensive mesenteric nodal involvement. Of the 17 patients, 12 (71%) had at least one symptom referable to the gastrointestinal tract, while 5 (29%) were clinically asymptomatic. Fourteen of the 17 patients (82%) had additional intraabdominal metastases to sites other than small bowel and mesentery.
对230例诊断为恶性黑色素瘤的患者（310次CT检查）的腹部CT进行回顾性分析，以评估小肠和肠系膜受累情况。17例（7.4%）患者CT显示有小肠和肠系膜受累。有四种不同的疾病模式：（a）3例患者为腔内肿块；（b）2例为溃疡性病变；（c）6例为弥漫性浸润；（d）10例为种植转移。4例患者有两种以上受累模式。在10例有肿瘤种植转移的患者中，2例发现有癌性腹膜炎。2例患者发生肠套叠，4例有广泛的肠系膜淋巴结受累。17例患者中，12例（71%）至少有一项与胃肠道相关的症状，而5例（29%）临床无症状。17例患者中有14例（82%）除小肠和肠系膜外还有其他腹内转移。
