Brain capillary telangiectasia is usually a small collection of dilated capillary-like vessels. In most cases it is a harmless incidental finding with no clinical significance. They are most commonly located in the pons. In terms of image morphology, they show brush-like signal extinction in T2*/SWI (susceptibility-weighted imaging) sequences and contrast enhancement in T1-weighted images. Other sequences are usually unremarkable unless they involve unusually large capillary telangiectasias. Angiographically they usually remain silent. Sometimes they are associated with venous abnormalities and/or cavernomas. Their distinctive radiographic features usually allow for a reliable diagnosis. Differential diagnostic considerations, such as differentiation from a tumorous or inflammatory process, are sometimes necessary.
脑毛细血管扩张症通常是一小簇扩张的毛细血管样血管。在大多数情况下，它是一个无害的偶然发现，没有临床意义。它们最常见于脑桥。在图像形态学方面，它们在T2*/磁敏感加权成像（SWI）序列中表现为毛刷样信号缺失，在T1加权图像中表现为强化。除非涉及异常大的毛细血管扩张症，否则其他序列通常无明显异常。血管造影时它们通常不显影。有时它们与静脉异常和/或海绵状血管瘤相关。其独特的影像学特征通常可作出可靠诊断。有时需要进行鉴别诊断，例如与肿瘤性或炎性病变相鉴别。
