[Clinical picture and diagnosis of systemic angioreticulomatosis].

Among 131 patients with angioreticulomas of different parts of the central nervous system 16 and systemic angioreticulomatosis, which in half of the patients was in the form of multifocal lesion within the boundaries of the central nervous system, and in the remaining patients, in the form of the Hippel-Lindau syndrome. The authors point out frequent recurrence of this pathological condition, relatively poor results of surgical treatment, and the difficulty of intravital diagnosis, particularly in the case of asymptomatic visceral pathology in the Hippel-Lindau disease. The complex of diagnostic measures included total computer tomography which allowed systemic angioreticulomatosis to be verified in different stages of its clinical development.

[Method of highly sensitive electrothermometry for intraoperative diagnosis of supratentorial brain tumors].

The authors suggest a method of highly sensitive electrothermometry tested on 56 patients with extra- and intracerebral tumours of the brain matter of supratentorial localization. This method makes it possible to determine the localization, boundaries, dimensions and character of the tumour during the operation, which is essential for its subsequent removal with the least possible injury to surrounding tissues.
