Complicated Mastoiditis-MRI

  • Fluid signal in the right mastoid suggesting right mastoiditis. Peripherally enhancing extra-axial area in the right temporal region suggesting epidural abscess with associated altered signal in the squamous temporal bone and extension into the massetric space. Focal ring enhancing lesion with extensive perilesional edema is noted in the right temporal lobe suggesting temporal lobe abscess (1.4 x 1.2cm).  Prominent leptomeningeal enhancement is noted in right temporal region.  There is resultant mass effect with uncus indenting the right cerebral peduncle. 

Findings are suggestive of right mastoiditis with intracranial extension-epidural and intraparenchymal abscess & meningitis.
