Summary:

Description
  • Radiopaedia case ID: 82779
  • Image ID: 53610225
  • Image stack position: 33/71
  • Plane projection: Coronal
  • Aux modality: C+ arterial phase
  • Modality: CT
  • System: Central Nervous System
  • Findings: Non-contrast study is largely normal although, with the benefit of the perfusion findings, it is possible to vaguely make out hypodensity in the PICA territory on the right. A hyperdense "dot" is present posterior to the medulla and in the inferior 4th ventricle that suggests a hyperdense artery sign. Perfusion maps demonstrate an area of reduced CBF and CBV and elevated MTT and TTP conforming to the right PICA territory. CT angiography confirms non-opacification for the right PICA. The right vertebral artery is irregular as it passes through the dura consistent with a dissection.
