First report of adult Taenia solium in human brain with neurocysticercosis: illustrative case

The discovery underscores critical gaps in diagnostics, as the lesion mimicked metastatic cancer radiologically, and therapeutics, as standard cysticidal drugs target larval stages, not adult worms. This report highlights the urgent need to investigate interactions between parasitic infections and oncological interventions. It calls for updated clinical guidelines to address this novel pathogenic mechanism and emphasizes the importance of integrating parasitological expertise into neurological care. https://thejns.org/doi/10.3171/CASE25370.
