[Course of the hypertensive syndrome in spongioblastoma multiforme].

Of 140 patients with brain tumors of a supratentorial localization, in 50 cases a multiform spongioblastoma was established; it was verified either by a surgical operation, or during section. Three variants of the hypertensive syndrome were distinguished: tumorous, pseudovascular, pseudoinflammatory. The morphological brain studies determined an expressed vascular and cellular reaction to the malignant tumorous process. In a pseudoinflammatory clinical variant inflammatory changes were more expressed, while in pseudovascular--vascular changes. An atypical clinical development of multiform spongioblastoma is determined by the localization of the tumor, its histological structure, infiltrating growth and intoxication stemming from the tumor.
