Primary pontine haemorrhage: clinical and computed tomographic correlations
Journal of Neurology, Neurosurgery, and Psychiatry
|April 1, 1986
Summary
Primary pontine hemorrhage, often linked to hypertension, typically causes rapid neurological decline. Computerized tomography (CT) reveals brainstem hematomas, with many extending to other brain regions, though some resolve over time.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Primary pontine hemorrhage is a critical neurological event.
- Hypertension is a significant risk factor.
- Vascular malformations can be associated.
Purpose of the Study:
- To review clinical and CT findings in primary pontine hemorrhage.
- To correlate imaging findings with clinical outcomes.
- To describe the natural history of pontine hematomas on CT.
Main Methods:
- Retrospective review of 40 patients with primary pontine hemorrhage.
- Analysis of clinical data and computerized tomographic (CT) scans.
- Correlation of CT findings with patient outcomes and follow-up scans.
Main Results:
- 29 patients were hypertensive; 4 had vascular malformations.
- 33 patients experienced rapid neurological deterioration.
- CT showed hyperdense, non-enhancing brainstem hematomas, often with ventricular extension (27 cases).
- Hematoma extension to the midbrain (26 cases) and thalamus (4 cases) was observed.
- Five patients survived, with four regaining independence within 3 months.
- Follow-up CT in 6 cases showed hematoma resolution without enhancement.
Conclusions:
- Primary pontine hemorrhage presents with diverse clinical courses and CT findings.
- CT is crucial for diagnosing and characterizing pontine hematomas and their extensions.
- Pontine hematomas typically resolve on follow-up CT without enhancement.
