OBJECTIVE
The objective of this study was to describe the CT features of gastrointestinal schwannomas with clinicopathologic correlation.
CONCLUSION
Gastrointestinal schwannomas are uncommon mesenchymal neoplasms that are uniquely different tumors from their soft-tissue and central nervous system counterparts. They are homogeneously attenuating, well-defined, mural masses on CT. The lack of low-attenuation hemorrhage, necrosis, and degeneration within the tumor may help distinguish these tumors from gastrointestinal stromal tumors on CT.
目的
本研究的目的是描述胃肠道神经鞘瘤的CT特征并与临床病理进行相关性分析。
结论
胃肠道神经鞘瘤是罕见的间叶性肿瘤，与软组织和中枢神经系统的同类肿瘤有独特的差异。它们在CT上表现为均匀强化、边界清晰的壁内肿块。肿瘤内缺乏低密度出血、坏死和退变，这可能有助于在CT上将这些肿瘤与胃肠道间质瘤区分开来。
