Insights
Deep intracerebral hemorrhages are the most common type of spontaneous brain bleeding, often affecting the thalamus. This condition peaks in patients aged 61-70 and is frequently linked to high blood pressure and headaches.
Area of Science:
- Neurology
- Radiology
- Epidemiology
Background:
- Spontaneous intracranial hemorrhage is a significant cause of morbidity and mortality.
- Understanding the epidemiological and radiological characteristics is crucial for diagnosis and management.
Purpose of the Study:
- To identify the most frequent computed tomography (CT) findings in patients with spontaneous intracranial hemorrhage.
- To analyze the demographic and clinical features associated with different types of intracranial hemorrhages.
Main Methods:
- Retrospective analysis of computed tomography (CT) scans from 250 patients diagnosed with spontaneous intracranial hemorrhage.
- Data collection included hemorrhage location, patient demographics, symptoms, and blood pressure levels.
Main Results:
- Deep intracerebral hematomas showed the highest incidence, followed by lobar hemorrhages, with the thalamus being a common site.
- Peak incidence occurred in the 61-70 age group. Headache and hypertension were the most frequent associated symptoms.
- Cerebellar and brainstem hemorrhages were less common. Hemorrhage into the ventricular system was more frequent in deep hematomas.
Conclusions:
- Deep intracerebral hemorrhages are the predominant type, often involving the thalamus and associated with hypertension.
- CT imaging is vital for characterizing spontaneous intracranial hemorrhage, guiding clinical decisions.
- While age and hypertension are key factors, earlier onset in males warrants further investigation.
Abstract:
Computed tomography studies of 250 patients with spontaneous hemorrhage were examined in three hospitals in the city of Rio de Janeiro. The goal of this study was to identify the aspects of this disease that appear most frequently in this type of exam. Deep intracerebral hematomas have had the highest incidence followed by lobar hemorrhage, with thalamus being more frequently affected. Cerebellar hemorrhage was much rarer, with brainstem bleeding observed in few patients. The age group with a peak incidence was at 61 to 70 years. Headache was the most frequently related symptom and elevated levels of blood pressure were found in most of the cases. There was no pronounced difference as to predominance in either sex or side most affected but it was observed that the onset of this disease occurs at an earlier age in men than in women. Blood draining into the ventricular system occurred more frequently in deep hematomas.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
