title: [Single-photon emission-computed tomography of the brain in craniopharyngiomas in the late postoperative period].
abstract: The paper analyzes tomographic scanning images of 32 patients with craniopharyngiomas in the late postoperative period. Computed tomographic data allowed the patients to be divided into 3 groups: 1) 10 patients without signs of tumor recurrence or hydrocephalus; 2) 14 patients with recurrent cystic craniopharyngiomas; 3) 8 patients with severe hydrocephalus. Single photon emission computed tomography (SPECT) of the brain indicated regional disturbances of brain tissue blood supply in the frontobasal or frontobasotemporal regions of the right hemisphere (the area of an surgical access and of the removed tumor) and revealed them in the distal areas (frontobasotemporal regions of the left hemisphere, parietal and occipital cortices of the cerebral hemisphere or cerebellar tissue). The compensatory reserves of cerebral circulation were assessed by the foci of relative physiological hyperemia of brain tissue (the cerebellum and the medial portions of the occipital regions of the brain). The findings provide evidence for that the vascular factor is involved in the late postoperative pathological picture in patients with craniopharyngiomas.
