[Myeloscintigraphic findings in a case of intradural leptomeningeal cyst]

The authors report the application of myeloscintigraphy in a case of intradural leptomeningeal cyst. Only 16 such cases have been described as yet in world literature. Myeloscintigraphy was found in this case a more objective and accurate method than myelography and permitted not only the compressing mass to be recognized but it determined also the upper and lower limits of the mass which is important for surgical intervention.
