Abstract
We present CT and MR imaging studies of a histologically proved case of a primary intraaxial amyloidoma of the brain. Noncontrast CT and T1-weighted MR images revealed increased density and hyperintensity respectively of amyloid tissue. There was mixed intensity on proton-density and T2-weighted sequences, and marked contrast enhancement was demonstrated on both modalities.
摘要
我们展示了一例经组织学证实的原发性脑内轴突淀粉样瘤的CT和MR成像研究。平扫CT和T1加权MR图像分别显示淀粉样组织密度增加和信号增强。质子密度和T2加权序列呈混合信号强度，两种检查方式均显示明显的对比增强。
