title: Gliomatosis cerebri--an appropriate diagnosis? Case reports.
abstract: OBJECTIVE
  To evaluate the premises for the diagnosis gliomatosis cerebri in relation to diffuse astrocytomas.
  
  
  METHODS
  CT, MR images and pathological analyses were used to assess the cases of 4 patients with diffusely infiltrating astrocytic tumours that radiologically, clinically and pathologically resembled gliomatosis cerebri.
  
  
  CONCLUSIONS
  Some astrocytomas have an immense potential for diffuse infiltration and they would seem to be more frequent than recognized hitherto. The definition of gliomatosis cerebri as a separate entity is questionable, and a diagnosis of diffusely infiltrating astrocytoma is recommended in such cases.
