An irregular, \u2018moth-eaten\u2019 bone destruction pattern was seen on high-resolution computed tomography images, most commonly in the eustachian tube (9\/13), jugular foramen (9\/13) and facial nerve canal (7\/13). On non-contrast magnetic resonances images, masses were isointense or slightly hypointense on T1-weighted images, and isointense or slightly hyperintense on T2-weighted images. On post-contrast images, lesions were moderately and homogeneously enhanced in seven cases and inhomogeneously enhanced in six.<\/jats:p><\/jats:sec>Conclusion:<\/jats:title>High-resolution computed tomography precisely detects regions of bone destruction, whereas MRI can better assess soft-tissue tumour margins, intracranial extension and vessel patency.
