Fourteen cases are described in which surface enhancement of the brain or spinal cord was observed on magnetic resonance (MR) scans performed using the paramagnetic intravenous contrast agent gadolinium-DTPA. The sign was seen in cases of meningioma, extradural haematoma, neurosarcoidosis and after surgery and radiation therapy for malignant tumour. This sign is demonstrated on MR with increased sensitivity compared with computed tomography, and is useful in indicating dural attachment of meningiomas. It may also be of value in the presence of meningeal inflammatory changes from a variety of causes.
本文描述了14例在使用顺磁性静脉造影剂钆喷酸葡胺进行的磁共振（MR）扫描中观察到脑或脊髓表面强化的病例。该征象见于脑膜瘤、硬膜外血肿、神经结节病以及恶性肿瘤手术后和放疗后。与计算机断层扫描相比，MR对该征象的显示敏感性更高，有助于提示脑膜瘤的硬膜附着情况。在各种原因引起的脑膜炎症改变时，它可能也有价值。
