[Capillary telangiectasia of the pons].
Three observations of teleangioectases of the Varolian bridge verified at a histological examination are presented. In one of the cases the telangioectases were concurrent with an astrocytoma of the left hemisphere, and were a casual finding. In another case the teleangioectases have led to a massive hemorrhage to the Varolian bridge and the patient's death. In the third case the teleangioectases were revealed at the histological examination of the Varolian bridge affected by an astrocytoma. The development of the tumour was, possibly, due to reactive gliosis withing the zone of a vascular developmental defect. Clinical, roentgenological, pathomorphological, and histological data are presented. The authors point out that histological examinations are obligatory in cases of hemorrhages to the Varolian bridge, so that their origin should be properly documented.
