Contrast enhancement is essential for diagnosis of leptomeningeal tumor.  Thick enhancement of the spinal cord surface and nerve roots is the characteristic finding in the spine.  Nodular cord surface or dural-based deposits may be seen in patients with more extensive disease.  In the brain, carcinomatous meningitis is characterized by thick enhancement of the basilar cisterns and of the leptomeningeal surfaces.  Thick, linear enhancement of the cerebral sulci and folia of the cerebellum is characteristic.

增强有强化是软脑膜肿瘤的首要表现，脊髓和神经根表面厚层强化，是脊柱的特征表现。脊髓表面结节和硬脑膜底部沉积物可见于其他更多疾病的患者。在头部疾病中，转移性癌性脑膜炎特征表现为基底池和软脑膜表面的厚层强化。脑沟和小脑薄层的厚层、线样强化是特征性表现。
