Imaging findings for neurocysticercosis depend on location and stage of infection.
Parenchymal cysts usually involve the grey-white matter junction.
In nodular calcified, long-term enhancement may be evident on MRI and may predict ongoing seizures.
Neurocysticercosis (NCC)Â is caused by theÂ CNS infectionÂ with the pork tapeworm Taenia solium.
Clinical presentations include seizures, headaches, hydrocephalus, altered mental status, and neurological defects.
Extra-intestinal infection undergoes specific clinical and imaging changes as it progresses through four stages of infection.
There are four main stages (also known as Escobar’s pathological stages).
It is the most common cause of epilepsy in endemic areas (Southeast Asia, South America) with progression through the four stages taking anywhere between 1 to 9 years.
Differential diagnoses include cerebral metastases and tuberculoma.
