case_images: Preoperative MR images. a, b Axial and parasagittal T2-weighted MRI scans showing an inhomogeneous hyperintense prepontine lesion with a mass effect on the brainstem. c, d Axial and parasagittal T1-weighted MRI scan after administration of gadolinium contrast show inhomogeneous enhancement. e Axial T1-weighted MRI scan shows an inhomogeneous hypointense prepontine lesion. f Parasagittal constructive interference steady state (CISS) MRI scan shows an inhomogeneous hyperintense prepontine lesion

case_images: After administration of IV gadolinium, there was some inhomogeneous enhancement (Fig. 1).
case_images: Postoperative MR images. A complete tumour removal is shown on the a parasagittal T1-weighted sequence, b axial T2-weighted sequence and c axial T1-weighted sequence after administration of gadolinium contrast

case_images: The postoperative MRI showed a complete removal of the tumour (Fig. 2).
case_images: Histopathological imaging. The lesion shows vacuolated tumour cells with a pale cytoplasm and moderate nuclear polymorphism in a chondromyxoid matrix. These findings are a characteristic of chordoma
