Imaging is usually best
CT head (calcifications/edema); MRI (cysts +/- scolex, edema)
X-rays or CT for extraneural<unk> 
EITB assay for anticysticercal antibody
Serum (more sensitive) or CSF studies (less common)
Labs
Usually not helpful
Eosinophilia not seen unless cyst is leaking/ruptured

Definitive: 1 absolute criterion, or 2 major plus 1 minor and 1 epidemiologic criteria.
Probable: 1 major plus 2 minor criteria, or 1 major plus 1 minor plus 1 epidemiologic criteria, or 3 minor plus 1 epidemiologic criteria.
