RESUMO
We present five cases of Syringomyelia, three of which are associated with Arnold-Chiari malformation, establishing a comparison between the diagnostic effectivity of CT scan and Nuclear Magnetic Resonance (NMR). In all five cases the lesion was detected by NMR, but not by CT scan. The advantages of NMR over CT scan were evaluated concluding that NMR is more sensible and should be of first choice in the diagnosis of Syringomyelia, permitting also, a better study of the extension of the cavities as well as its control after surgical treatment.

A case of deficiency of cobalamin coenzyme synthesis whose first manifestation was encephalopathy with seizures and no trace of megaloblastic anemia is presented. After a while, signs of posterior cord and polyneural disfunction were detected. We highlight the rareness of the case and the difficulty of the diagnosis because of the discrepancy between neurologic and hematologic signs, as well as the need for early diagnosis which is an important factor for observing therapeutic response.
