Figure 1: (a) HRCT showing the lesion widening the right internal auditory meatus with erosion of floor of the middle cranial fossa. (b) T1-weighted MRI showing the lesion causing widening of the internal auditory meatus with extension to the middle cranial fossa abutting the temporal lobe. A small component of the lesion is also extending in the posterior cranial fossa. (c) MRI showing lesion in the right internal auditory meatus with extension to the middle cranial fossa base and a small component in the posterior fossa causing a dumb-bell shaped appearance of tumor
