【摘要】：目的探讨颅内神经管原肠囊肿的MRI表现特征。方法搜集6例经手术病理证实的颅内神经管原肠囊肿患者的MRI及相关临床资料,分析其发生部位、形态及信号特点等。结果 6例中,病灶位于桥前池1例,延前池1例,桥延交界前方2例,桥小脑角池、脚间池及鞍上池1例,桥前池、脚间池1例。2例呈类圆形,2例呈分叶状,1例呈类哑铃形,1例呈不规则分叶状。1例肿瘤明显嵌入脑干,类似"脊髓嵌入征"。MRI信号较多样,T_1WI多呈等或高信号,T_2WI多呈高或等信号,增强扫描无强化。结论颅内神经管原肠囊肿的MRI表现有一定特征,对诊断及鉴别诊断有重要价值。
[Abstract]:Objective to investigate the MRI features of intracranial neurotubule enterocele. Methods MRI and related clinical data of 6 patients with intracranial neurotubule cysts confirmed by operation and pathology were collected and their location, morphology and signal characteristics were analyzed. Results among the 6 cases, 1 case was located in the anterior pontine cistern, 1 case in the protuberant cistern, 2 cases in the anterior part of the Pontine junction, 1 case in the cerebellopontine angle cistern, 1 case in the interpeduncular cistern and 1 case in the suprasellar cistern. The interpeduncular cistern in 1 case, 2 cases were round, 2 cases were lobular, 1 case was dumbbell-like, 1 case was irregular lobular shape, 1 case was obviously embedded into the brain stem, similar to "spinal cord embedding sign" .MRI signal intensity was more varied than that on T1WI, most of them showed iso-signal or hyperintense signal on T _ 2WI, and most of them showed high or equal signal intensity on T _ 2WI. Enhanced scan without enhancement. Conclusion the MRI features of intracranial neurotubule cysts are of great value in the diagnosis and differential diagnosis.
