[Intradural clivus chordoma: surgical treatment with no tumor regrowth 12 years after surgery].

We present a case of a 19-year-old woman treated in the Neurosurgery Department of Collegium Medicum of the Jagiellonian University in Kraków because of the clival chordoma. The patient with one year anamnesis, treated surgically and then rehabilitated, was examined 12 years after she left our department. Radiologically we did not find tumor regrowth. We only found diplopia, but this sign was present from the time of the operation. Such a long time of katamnesis proves possibility of total removal in this type of tumors.
