Abstract

MR imaging and CT were performed in eleven patients with intracranial cysticercosis to compare each finding sand to evaluate the capability of MR in demonstarating any additional findings to CT especially inintraventricular cysticercosis. The MR image were obtained using either 0.15 Tesla resistive or 2.0 Teslasuper conductive system with various pulse sequences including inversion recovery, T1-weighted spin echo and T2-weighted spin echo in axial, sagittal and/or coronal planes. MR was superior to CT is 5 cases; The intraventricular nodule or scolex not visible on CT was demonstrated in 3 cases and it appeared more porminent ofMR than on CT in one case. Perifocal edema around the parenchymal lesions and subependymal or subpial high signalrims of tissue reaction around the ventriculocisternal cysticerci were more sensitive on MR in 4 cases. MR wasinferior to CT in 2 cases; MR failed to visulize multiple pin-point calcifications in 2 cases and meningeal enhancement in one case, while CT demonstrated above lesions. MR was equal to CT in other than above. The cysticfluid of cysticercosis was not distinguishable from cerebrospinal fluid (CSF) on MR with various TR and TE in mostcases. But, visible intraventricular nodule and subependymal tissue reactions on MR with various TR and TE in mostcases. But, visible intraventricular nodule and subependymal tissue reactions on MR strongly suggest ventricularcysticerci and may replace the invasive ventriculography.
