Abstract

We report two cases of pathologically proven intracranial epidermoid cysts. Both cases were scanned with diffusion-weighted imaging using pulsed gradient spin-echo (PGSE) and oscillating gradient spin-echo (OGSE; 50 Hz) prototype sequences with diffusion times of 47.3 ms and 8.5 ms, respectively. The apparent diffusion coefficient measured by OGSE was higher than that measured by PGSE, indicating the spatial restriction of water diffusion in the laminated keratin layers within the cyst as demonstrated by histopathology.

摘要

我们报告了两例经病理证实的颅内表皮样囊肿。这两例均使用脉冲梯度回波（PGSE）和振荡梯度回波（OGSE；50 Hz）原型序列进行扩散加权成像扫描，扩散时间分别为 47.3 ms 和 8.5 ms。OGSE 测量的表观扩散系数高于 PGSE 测量的表观扩散系数，表明囊内层状角蛋白层中水扩散的空间限制，这与组织病理学结果一致。
