Preoperative computed tomography and magnetic resonance imaging: a axial non-contrast computed tomography (CT) scan showing a slight hyperdense lesion lying in the prepontine cistern; b, c axial T1- and T2-weighted magnetic resonance imaging (MRI) demonstrated a hyperintense mass in the prepontine cistern, the basal artery was enveloped and the brainstem was compressed; d axial FLAIR image shows a hyperintense extra-axial cyst compared with CSF; e, f sagittal and coronal enhanced MRI scans demonstrate a heterogeneously non-enhanced ovoid mass located ventral to pons and medulla
