The neurocysticercosis intra-rachidian form is quite rare, the intradural-extramed-ullary presentation being the most frequent and the intramedullary, the less frequent. Among 205 , SP, Neurology Service, in the period between 1961 and 1987, only 18 (9.0%) had a definite diagnosis of neurocysticercosis, and only three (1.4%) presented intradural-extramedullary spinal infestation by cysticercosis(5).
In the literature, we have found an excellent review study analyzing 95 cases of spinal cysticercosis published since 1865 (Chart 1), 61 (66.0%) of them presenting intradural-extramedullary localization, and 33 (34.0%) presenting intramedullary localization(4). Many studies included in this review and other more recent studies(1,3,6), likewise the present case, have shown the simultaneous involvement of liquoric, intradural-extramedullary spinal spaces in different segments and cerebral spaces.
