Figure 1: (a) Computed tomography scan (axial view) showing a hyperdense lesion in the right cerebellopontine angle with broad attachment toward petrous bone; (b) computed tomography scan (axial view) showing extra-axial hyperdense lesion with broad attachment toward petrous bone with effacement of the 4th ventricle, torsion of the brain stem with previous craniectomy defect; (c) T1-weighted axial magnetic resonance imaging image with contrast showing extra-axial lesion in the right cerebellopontine angle; (d) T1-weighted image coronal magnetic resonance imaging image with contrast showing a lesion involving right-sided posterior fossa dura-based mass with dural enhancement
