case_images: MRI (a) Sagittal T2-weighted MRI showing a large posterior fossa ependymoma, extending from the fourth ventricle to the C2 level. (b) Axial T1-weighted MRI with contrast, showing a fourth ventricle ependymoma passing by the foramen of Margendie

case_images: Magnetic resonance imaging (MRI) demonstrated the existence of a large lesion, suggestive of ependymoma, which extended from the floor of the fourth ventricle, emerged from the foramen of Magendie and descended to the C2 level [Figure 1].

case_images: Therefore a brain computed tomography (CT) was carried out immediately after surgery [Figure 3], which showed multiple supratentorial hemorrhages.
