Abstract
Capillary telangiectasias are being recognized with increasing frequency on MR imaging studies. Most are located in the brain stem and show slightly increased signal intensity on T2-weighted images, low signal intensity on T2*-weighted images (reflecting the presence of deoxyhemoglobin), and contrast enhancement. These findings are considered fairly typical for capillary telangiectasia, and pathologic correlation is not generally pursued. We present a case of a proven capillary telangiectasia in the basal ganglia. The imaging features of the lesion were identical to those described for capillary telangiectasias in the brain stem.
摘要
在磁共振成像研究中，毛细血管扩张症的检出频率越来越高。大多数位于脑干，在T2加权图像上信号强度略有增加，在T2*加权图像上信号强度较低（反映脱氧血红蛋白的存在），并伴有对比增强。这些表现被认为是毛细血管扩张症的相当典型的特征，一般不进行病理对照。我们报告一例基底节区经证实的毛细血管扩张症病例。该病变的影像学特征与脑干毛细血管扩张症的描述相同。
