A hidden traveler in the brain: A 19-year odyssey of migratory cerebral sparganosis

This case highlights the remarkable ability of Sparganum larvae to survive within human brain tissue for nearly two decades, with evidence of active intracerebral migration. Surgical excision remains the most definitive and effective treatment approach. Due to the potential for delayed diagnosis and chronic progression, long-term imaging follow-up and continued clinical awareness are essential for early recognition and successful management, even in regions where sparganosis is not commonly encountered.
