Axial and sagittal post contrast T1-weighted enhanced MR scan around
Eustachian tube scan confifirming
SBO extending from the right to the left along cranial base bone,
prevertebral space( red arrow) with little abscesses ( green
arrow),enhancement of the thickened dura(blue arrow)and parapharyngeal
tissue.Meningeal enhancement is a evidence of convincing intracranial
extension.Images shows the diffuse infective lesions improved by both of
mastoidectomy(yellow arrow)and voriconazole(pink arrow),but the
extending lesions cannot be prevented by surgery.
