RESUMO
The authors describe various new neuroradiological findings in cysticercosis cerebri. Features discussed include: (a) contrast enhancement in cysticercosis, including enhancement of an intraventricular cyst, basal meningeal enhancement, and enhancement in association with granulomatous reaction to cysticercosis; (b) positional cyst alterations, including cyst mobility and positional changes in cyst configuration; (c) neuroradiological features of foramen of Monro obstruction, which may be unilateral or bilateral, and may be due to cysts or adhesions; and (d) unusual angiographic features, including two cases of ring stains which corresponded to ring enhancement on CT, and a mycotic aneurysm associated with cysticercosis. For this study, the authors evaluated 102 cases of cysticercosis; 12 case reports are presented herein.
