摘要
颅内神经源性囊肿并不常见，通常在T1加权像上呈低信号，在T2加权像上呈高信号。我们报告一例位于延髓前面的神经肠性囊肿，其大小随着MR信号由高信号变为等信号而增大，在初始MR图像33个月后获得的T1加权图像上，其大小与脑的T1加权图像相比增大。我们认为，包囊的信号变化可能是由于蛋白质浓度的变化引起的。
SUMMARY
Intracranial neurenteric cysts are uncommon and usually have low intensity on T1-weighted MR images and high intensity on T2-weighted MR images. We report a case of a neurenteric cyst that was situated in front of the medulla oblongata and the size of which increased with alteration of MR signal from high to isointense compared with that of brain on T1-weighted images obtained 33 months after the initial MR images. We think that the signal change of the cyst was probably caused by a change of protein concentration.
