title: Myelography in metastatic lesions.
abstract: The radiologic appearances at gas myelography were analysed in 57 metastatic lesions, all histologically verified, or having known primary tumours. Five of these cases were also examined with a water-soluble contrast medium, metrizamide. The results were correlated to the findings at surgery and to tumour pathology. It is concluded that myelographic findings simulating juxtamedullary growth are usually due to local indentation of the dura by the extradural tumour, and not to intradural extension.
