Spanish Man's Brain Tapeworm Misdiagnosis

A 60-year-old man in Spain was initially misdiagnosed with metastatic brain cancer after presenting with headaches and behavioral changes. Further detailed MRI scans revealed that the 'tumors' were actually fluid-filled cysts containing larvae of the pork tapeworm (Taenia solium), a condition known as neurocysticercosis. The patient, a lifelong resident of Castellon, had no travel history to endemic regions, suggesting a rare case of local transmission, possibly through fecal-oral contact with migrant coworkers. He was successfully treated with antiparasitic medications, Albendazole and Praziquantel, and corticosteroids. The case, published in the United States — Centers for Disease Control and Prevention journal Emerging Infectious Diseases, emphasizes the need to consider parasitic infections in differential diagnoses even in non-endemic areas to prevent unnecessary invasive procedures.
