Summary:

Description
  • Radiopaedia case ID: 88756
  • Image ID: 54865184
  • Image stack position: 203/208
  • Plane projection: Axial
  • Aux modality: T1
  • Modality: MRI
  • System: Head & Neck
  • Findings: Bilateral normal cochlear size. The internal auditory meati are enlarged, with complete absence of modioli and spiral laminae, but present interscalar septa, demonstrating a "corkscrew" appearance. Vestibules and semicircular canals are irregularly shaped with cystic bulges. Findings are in keeping with cochlear incomplete partition (IP-III). Dysmorphic, nonenhancing aspect of hypothalamus that follows cortical signal in all sequences, typical of hamartoma. Area of white-gray matter junction blurring at the posterior aspect of the left superior temporal gyrus, associated with minimal cortical thickening and hyperintense white matter on FLAIR, in keeping with a Blumcke type I focal cortical dysplasia.
