摘　　要：目的分析肠系膜侵袭性纤维瘤病的多层螺旋CT表现。方法 6例经手术病理证实的肠系膜侵袭性纤维瘤病患者术前均接受多层螺旋CT平扫和增强扫描。结果 6例病灶均为单发,最长径平均为15cm;4例病灶形态规则呈类圆形,2例呈分叶状;4例病灶与周围肠管分界清晰,2例病灶侵犯局部小肠,肿块内可见气体影。CT平扫4例病灶呈均匀软组织密度,2例病灶呈混杂密度,其中1例病灶内有气-液平面,1例病灶内有囊变区。增强扫描病灶以轻-中度强化为主,内见散在小斑片状明显强化区,3例可见肠系膜血管分支进入肿块。所有病灶均无钙化,腹腔及后腹膜无肿大淋巴结、无腹腔积液。结论提高对CT征象的认识是正确诊断肠系膜侵袭性纤维瘤病的关键。Objective To analyze multi-slice CT characters of mesenteric aggressive fibrotomasis. Methods Six patients with aggressive mesenteric fibromatosis proved by surgery and pathology were reviewed. All the patients had preoperative multi-slice CT precontrast and enhanced examinations. Results Singular lesion located in the mesentery was found in all the 6 patients. The mean longest diameter of tumors was 15 cm. The shape of tumor was ovoid in 4 patients and lobulated in 2 patients. Four tumors had well defined edges and sharply marginated from small bowel loops, whereas other 2 infiltrated the adjacent small bowel loops and had air accumulation. On precontrast CT images, 4 tumors were homogeneous, similar to that of soft tissue, while 2 tumors had mixed density, of which 1 was heterogeneous because of air-fluid level and the other had part of cysts. Enhanced CT scans revealed that the most part of tumors had mild to moderate enhancement with several high-enhanced patchy, and ingression of mesenteric artery branches in 3 tumors. No calcification was observed in all the tumors. None of 6 patients had ascites and lymphadenectasis in the mesentery or retroperitoneum. Conclusion To improve knowledge of the manifestations of aggressive mesenteric fibromatosis is the key to increase diagnostic accuracy.
