Abstract

TUMORS of the pons are not common. McLean1 stated: "The slowly growing, relatively infrequent tumors of this region produce a kaleidoscopic wealth of signs which are myriad combinations of nuclear paralyses and projection-tract disturbances, a neurologic delight for diagnosis and neurosurgical despair for therapeusis."

The vascular tumors constitute only a very small portion of these tumors and are thus extremely rare.

A certain confusion still prevails with regard to the nomenclature of the vascular tumors of the central nervous system. Virchow2 classified the angiomatous anomalies as follows:

  1. Cavernous angiomas, i. e., vascular tumors made up of dilated "cavernous" spaces with fused walls, so that neither glia nor specific nerve tissue, but only a sparse stroma resembling connective tissue, is found between the spaces

  2. Vascular changes in which glia or nerve tissue is present between the individual lumina

    • Telangiectases (or simple angiomas), consisting of vessels of capillary structure

    • Racemose
