Diagnosis: Neurocysticercosis
Vesicular presents with cyst with dot sign.
In granular nodular, cyst retracts.
Neurocysticercosis (NCC) is caused by a CNS infection with the pork tapeworm Taenia solium.
CSF serology may be helpful with the initial diagnosis, especially in cases of intraventricular/subarachnoid infection.
Infection, which leads to extra-intestinal disease (including neurocysticercosis), usually occurs as a result of eating food or drinking water contaminated by human feces containing T. solium eggs.
Extra-intestinal infection undergoes specific clinical and imaging changes at it progresses through four stages of infection.
Typically the parenchymal cysts are small (1 cm), whereas the subarachnoid ones can be much bigger (up to 9 cm).
General imaging differential considerations include cerebral metastasis.
