Introduction:

the term "brain tumor" refers to an unusual growth of tissue in the brain; all the structures that are part of the brain and its environment have cells that can grow in an uncontrolled way and produce tumor lesions.

Objective:

to characterize adult patients, with brain tumors of glial origin, attended at the General Teaching Hospital "Agostinho Neto", in the period 2017-2021.

Methods:

an observational, descriptive, cross-sectional study was conducted in patients diagnosed with astrocytic tumor. From a population of 80 patients, a probabilistic, simple random sample of 40 patients was taken. The variables included in the study were: age, sex, debut symptom, syndrome, Karnoftsky scale value, histological diagnosis, Kernohan classification, topographic localization, tomographic density, edema association, displacement of midline structures.

Results:

it is observed that in terms of age, patients older than 40 years old stand out (n=34 85 %), female (n=22 55 %). The most observed syndrome was endocranial hypertension (n=22 55 %). The most common histological diagnosis was glioblastoma multiforme (n=18 45 %). The tomographically predominant lesions in patients were larger than 50 mm (n=30 75 %). In the case of survival, most patients were deceased (n=30 75 %).

Conclusions:

It is concluded that brain tumors are an entity that, in the research presented, shows a higher incidence in women, with a tendency to have a large size, behaving as tomographically heterogeneous lesions.
