  • Abstract
  • Look Inside

 The ultrastructure of the capillaries in human brain tumors was studied from the point of view of blood-brain barrier.

 Specimens of brain tumors were obtained at the time of surgery.

 Human brain tumors examined were 16 gliomas (Table 1), 8 neurinomas, 9 meningiomas, 5 pituitary adenomas, 1 hemangioblastoma, 1 choroid plexus papilloma and 2 metastatic tumors.

 1) In gliomas the hypertrophied capillary endothelial cells with irregular surface and villous process were characteristic and much more pinocytotic vesicles were observed than in those of normal brain (fig. 1, 3, 5, 7).
