[Primary osteosarcoma of the base of the skull in Garcin syndrome].

This contribution presents a case study of a 17-year-old female patient with unilateral failure of several brain nerves within a period of five months. Further findings included fleeting homolateral signs of the small brain and, during the terminal phase, discrete hemiparesis. Diagnosis was based on the tomograms of the skull base and computerized tomography, which revealed a tumour at the base of the skull. During the obduction this was found to be a primary osteosarcoma. According to the literature it is rare for this kind of tumour to lead to Garcin 's syndrome.
