| 目的 分析小肠间质瘤的影像学特点,探讨CT对该肿瘤的诊断价值。方法 回顾性分析经手术病理证实的21例小肠间质瘤CT的特点。并与临床病理学的表现进行对照。结果 21例患者共检出病灶25个,18例为单发,3例多发。以空肠较常见(11/25)。4例良性肿瘤直径1.5~3.5 cm,均为单发病灶。良性肿瘤CT平扫表现为类圆形的均匀软组织密度影,直径均小于4.0 cm,增强后均匀轻度强化。17例恶性肿瘤共21个病灶,每例均有1个病灶直径均大于4.0 cm,多为腔外生长,呈分叶状或不规则形,肿瘤常出现囊变坏死,瘤内可见气体或有口服对比剂,以及形成气液平,增强扫描呈环形或不规则强化,囊变坏死区不强化。肿瘤可转移至肝脏。以肿瘤直径是否大于4.0 cm评价肿瘤的良恶性,本组准确率可达100%。结论 小肠间质瘤在CT上有一定特征性,多表现为腔外或混合性生长的肿块,瘤内可见气体密度或对比剂影。CT可作为诊断小肠间质瘤的重要检查方法。 |

| Objective To analyze the CT imaging features of small bowel stromal tumors and to evaluate the CT diagnostic value of small bowel stromal tumors. Methods Twenty-one patients with small bowel stromal tumors were proved pathology and their CT findings with pathology correlation were analyzed retrospectively.Results This group included 21 patients with 25 lesions.Eighteen patients were solitary lesion and 3 patients were multiple lesions among 21 patients.The lesions were dominantly located in jejunum. The benign lesions (n=4) were round and small. Smaller 4.0 cm in diameter in plain CT scans, while the malignant lesions were lobulated or oval-shaped and large 4.0 cm in diameter, exophytic growth, air and medium within the tumor, or even cystis degeneration and necrosis. On enhanced CT scan, benign lesions showed slightly enhancemen, and the malignant lesions showed ring-shaped or uneven enhancement. While tumor >4.0 cm in diameter was regarded magligant,the diagnostic accurate was 100% in this group.Conclusion The CT imaging features of small bowel stromal tumors are very significant, often exophytic or mixed growth with air or medium.CT is the important method to diagnose the tumos. |
