  • Abstract
  • Look Inside

To understand the early stage of subdural neomem-brane (SN) formation, we examined 23 outer SNs and two inner SNs of chronic subdural hematomas in sur-gical specimens. Ultrastructurally, the cellular compo-nent of the outer SN was fibroblasts, myofibroblasts, smooth-muscle cells (in four cases), blood vessels and blood-born cells. Dural border cells were observed only in limited areas. Namely, the outer SN is a simple gra-nulation tissue which originates from multiple sources of mesenchymal cells in dura mater, and dural border cells are only one of constituent sources for SN formation.
