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.
