Cysticercosis, like other parasitic disease, is still endemic in many parts of the world, and is not infrequently found in Korea. The authors reviewed CT findings of 54 cases of the cysticercosis involving the central nervous system which were proven by pathology and clinical findings. The results are as follows: 1. Male to female retio is 3 : 1 and the most prevalent age group is the fifth decade. The most common sympton is seizure(56%). 2. Involved areas in the brain are parenchymal(66%), intraventricular(15%), leptomeningeal(40%) and the mixed(15%). 3. Pre-contrast CT findings are the round low density in 46 cases(85%), multiple pin-point calcification in 18 cases(33%), variable degrees of hydrocephalus in 20 cases(37%) and peripheral edematous change in 8 cases(15). 4. Post-enhancement CT findings are complete or partial wall enhancement in 28 cases(50%), nodular enhancement in 18 cases(32%) and pin-point enhancement in 10 cases(18%) which represents the enhancement of the scolex per se. Basal cisternal enhancement is seen in one case, which is very unusual finding of cysticercosis cellulosae.
