A 17-year-old woman presented with a rare case of intracranial seeding of craniopharyngioma after repeated surgery. She initially presented with secondary amenorrhea and visual impairment. Magnetic resonance imaging revealed a suprasellar mass. Subtotal removal of the tumor was performed. The diagnosis was adamantinomatous craniopharyngioma. Seven months later, the patient underwent a second operation for recurrence of the craniopharyngioma. Subsequently, ventriculoperitoneal (VP) shunting and gamma knife surgery were performed. Twenty-seven months after the first operation, multiple cystic lesions were found in the right frontal and temporal lobes. Positive tumor cytology was observed in the cerebrospinal fluid obtained from the VP shunt chamber. These tumors were subtotally resected. However, the patient died from consecutive tumor recurrence 4 years after the initial diagnosis.
