Magnetic resonance images of 44 patients who had varying degrees of supratentorial signal abnormalities compatible with subcortical arteriosclerotic encephalopathy (SAE) were reviewed for posterior fossa findings. Brain stem lesions frequently accompanied supratentorial SAE and were seen as multiple, fairly symmetric areas of poorly defined, increased signal intensity on axial T2-weighted images. Involvement was generally confined to the central portions of the mid and upper pons. The typical appearance of brain stem involvement by SAE and its probable pathogenesis are reviewed.
回顾了44例有不同程度幕上信号异常且符合皮质下动脉硬化性脑病（SAE）的患者的磁共振成像，以观察后颅窝表现。脑干病变常伴随幕上SAE，在轴位T2加权图像上表现为多个、相当对称的边界不清、信号强度增加的区域。受累通常局限于脑桥中上部的中央部分。本文回顾了SAE累及脑干的典型表现及其可能的发病机制。
