Autochthonous Neurocysticercosis Brain Lesions Mimicking Metastatic Disease, Spain

Autochthonous neurocysticercosis is exceptionally rare in Western Europe. We describe multiple brain lesions, initially mimicking metastases, in a 60-year-old man in Spain without travel history. We confirmed diagnosis by neuroimaging and positive serology. Our study highlights cryptic local Taenia solium nematode transmission risks and diagnostic challenges in nonendemic regions.
