Computed tomographic spectrum of neurocysticercosis.
Computed tomography (CT) is a very sensitive modality for the diagnosis of neurocysticercosis. Fifty eight patients were evaluated by plain radiography and CT scans. The initial presentation was as seizure disorder (33), raised intracranial tension (19), meningoencephalitis (5) and psychiatric manifestation (1). Histologically confirmed subcutaneous nodules were seen in 20 cases and ocular cyst in 2 cases. CT scan showed multiple calcification in 8 cases, disc lesions in 30,ring lesions in 3, and a combination of disc and ring lesions in another 13 cases. Low attenuation lesions were seen in 4 cases in combination with disc/disc and ring lesions. All 58 cases had supratentorial lesions while 19 cases had infratentorial lesions in addition. Perifocal or generalised oedema was seen in 33 and 11 cases respectively. The ventricles were compressed in one case, large in 2 cases and normal in the rest. CT scan is valuable in the diagnosis of neurocysticercosis. Its significance is different in the various clinical and radiological groups.
