Summary:

Description
  • Radiopaedia case ID: 15077
  • Image ID: 1387035
  • Image stack position: 9/32
  • Plane projection: Axial
  • Aux modality: ADC
  • Study description: MRI Brain + MRA
  • Study findings: Extensive involvement of the territory of the right MCA characterized on T2*, FLAIR and DWI/ADC. Time-of-flight MR angiograms reveal flow cut-off at the right proximal middle cerebral artery.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Acute ischemia of the right lenticulostriate territory results in obscuration of the lentiform nucleus ("blurred basal ganglia"), which appears hypoattenuated because of cytotoxic edema. Dense MCA sign as a result of thrombus or embolus. The detection of the extension of acute ischemic brain parenchyma with non-enhanced CT scanning was facilitated by soft-copy visual review at a PACS workstation by using variable, non-standard window width and center level settings (a so-called "stroke window", the second series) 2.
