[Computerized tomography in patients with neurocysticercosis with intracranial hypertension due to obstructive hydrocephalus: comparison with Dimer-X ventriculography]
The authors reviewed the alterations observed on computerized tomography (CT) examinations of 16 patients with increased intracranial pressure and obstructive hydrocephalus due to cerebral cysticercosis. Plain radiograms of the skull were available in all cases and Dimer-X ventriculography in 12 cases. In 7 cases there were radiologic signs of increased intracranial pressure. CT scan showed normal cerebral parenchyma in 9 cases and low density areas, with various size, with or without surround contrast enhancement, and/or small calcifications in the parenchyma. Hydrocephalus was the only alteration observed in the ventricular system in the case that the examination was done before ventricular drainage. Ventriculography was analyzed in other paper and permitted to situate the obstruction, determine its morphological characteristics and identify occuping space lesions within the ventricles. Comparison between ventriculography and CT scan made in the same period evidence that the former gives best information about the ventricular system and that tomography gives additional information about the cerebral parenchyma. In conclusion, CT scan and ventriculography are investigations that complete each the other for evaluation and diagnosis of cerebral cysticercosis.
