Contrast-enhanced magnetic resonance images (MRI) of three patients with subdural (SDE) and two with epidural empyemas (EDE) were reviewed. In each case, the capsule of the lesion demonstrated enhancement, and distinction between capsule and contents was obvious on contrast-enhanced images. In SDE, contrast-enhanced images clearly depicted thickening of the neighbouring dura mater and a co-existent brain abscess. In EDE, part of the displaced dura mater did not enhance, which facilitated differentiation from SDE. Contrast-enhanced MRI was thus of value in diagnosis.
回顾了3例硬膜下积脓（SDE）患者和2例硬膜外积脓（EDE）患者的对比增强磁共振成像（MRI）。在每种情况下，病变的包膜均有强化，在对比增强图像上包膜与内容物之间的区分明显。在硬膜下积脓中，对比增强图像清楚地显示了相邻硬脑膜增厚以及并存的脑脓肿。在硬膜外积脓中，部分移位的硬脑膜无强化，这有助于与硬膜下积脓相鉴别。因此，对比增强MRI在诊断中具有价值。
