Abstract:
Post-traumatic CSF fistulae and those affiliated with tumours on the skull base have so far been investigated by isotope cisternography, fluoresceine tests and polytomography. 12 patients have recently been studied by metrizamide CT cisternography. In acute post-traumatic cases difficulties arise in the differentiation between blood clots and the stream of contrast medium. The method was found to be useful in delayed CSF fistulae and tumour-associated cases.
