Diagnosis of cranial asymmetries in cerebral arteriovenous malformations
Journal of Computer Assisted Tomography
|April 1, 1979
Insights
Cranial asymmetry detected on computed tomography (CT) scans may indicate cerebral arteriovenous malformations in some patients. Early assessment of this asymmetry is recommended for individuals suspected of having these vascular brain abnormalities.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Cerebral arteriovenous malformations (AVMs) are complex vascular abnormalities in the brain.
- Diagnosis often relies on advanced imaging techniques.
- Subtle or associated findings can aid in early detection.
Purpose of the Study:
- To investigate the prevalence of cranial asymmetry in patients with cerebral AVMs.
- To determine if cranial asymmetry is a useful indicator for AVM diagnosis.
Main Methods:
- Retrospective review of computed tomography (CT) scans from 29 patients with cerebral AVMs.
- Analysis of precontrast CT scans for cranial asymmetries.
- Correlation of asymmetry findings with confirmed AVM diagnosis.
Main Results:
- Nine out of 29 patients (31%) demonstrated abnormal cranial asymmetries on CT.
- Two patients with asymmetry showed no other discernible abnormalities on precontrast CT.
- Cranial asymmetry was observed in a subset of patients with cerebral AVMs.
Conclusions:
- Cranial asymmetry can be an associated finding in patients with cerebral AVMs.
- Assessment of cranial asymmetry on CT may aid in the diagnostic process for AVMs.
- Routine evaluation for cranial asymmetry is suggested for patients with suspected cerebral AVMs.
Abstract:
Nine of 29 patients with cerebral arteriovenous malformations exhibited abnormal cranial asymmetries on computed tomography (CT). Two of these patients showed no other abnormalities on their precontrast CT scans. Assessment of cranial asymmetry is recommended in all patients suspected of having an arteriovenous malformation.
