A 45-year-old Brazilian man who had recently moved to Europe presented to the emergency department for a severe, drug-resistant headache. Physical, medical, and neurological examination results were unremarkable. A noncontrast head computed tomography scan detected small, scattered intracerebral cysts in the left basal ganglia with a punctate calcification eccentrically along the cyst wall (Figure, A), while other cysts showed no calcification (Figure, B). Brain magnetic resonance imaging (Figure, C and D) showed classic findings of parenchymal neurocysticercosis in the viable stage: small cysts with a mural nodule, representing the eccentrically located cysticercus larva and its scolex.1 The cystic fluid appeared clear, cerebral spinal fluid–like, and there were no signs of inflammatory reaction. Diagnostic confirmation was obtained with serology.
