TERMINOLOGY

  • Definitions

    • "Pachymeninges" (thick meninges): Dura
    • Leptomeninges (thin meninges): Arachnoid, pia
    • Extradural space (EDS)
      • Potential space between dura, skull; seen only in pathologic conditions (infection, hematoma, etc.)
    • Subdural space (SDS)
      • Potential space between inner dura, arachnoid; seen only in pathologic conditions
    • Subarachnoid space (SAS)
      • Normal cerebrospinal fluid (CSF)-filled space between arachnoid, pial-covered brain
    • Subpial space (SPS)
      • Potential space between pia, glia limitans of cortex
    • Perivascular space (PVS)
      • Pial-lined, interstitial fluid (ISF)-filled invagination along penetrating arteries
      • Key part of brain "glymphatic" system
