E. CerebralCysticercosis!!!
By larval form of Tenia Solium(Pork TW)......Dxic points:

1.emigrated Costarican man with seizure;
2. normal CSF despite multifocal ceribral Calcifide lesion=calcifide tissue cysts;
3.cerebral edema without focal sign=due to chronic basal meningitis;

Rx: 1.Praziquantal+Albenfdazole+undercover of steroid rx-as cerebral ICP may be raise
when tissue cysts start getting necrosed.
2.Antiseizure drug.
