Summary
Ultrasound imaging of the brain can detect brain edema surrounding cortical mass lesions. This edema appears as a diffusely echo-genic white matter on sonography, correlating with CT findings.
Area of Science:
- Neuroimaging
- Medical Ultrasound
- Neuroradiology
Background:
- Cortical mass lesions can cause significant complications.
- Brain edema is a common complication associated with intracranial lesions.
- Accurate detection of brain edema is crucial for patient management.
Purpose of the Study:
- To evaluate the utility of sonography in identifying brain edema associated with cortical mass lesions.
- To compare sonographic findings with computed tomography (CT) in patients with cortical mass lesions.
Main Methods:
- Sonographic examination of the brain was performed in 10 patients.
- Patients had confirmed cortical mass lesions.
- Sonographic results were compared with CT findings.
Main Results:
- Brain edema was consistently identified surrounding the cortical mass lesions in all patients.
- Adjacent white matter showed a diffusely echo-genic appearance on sonography.
- This echo-genic appearance correlated directly with areas of brain edema observed on CT scans.
Conclusions:
- Sonography is a viable tool for detecting brain edema around cortical mass lesions.
- The diffusely echo-genic white matter pattern on ultrasound is indicative of edema.
- Ultrasound findings correlate well with CT in assessing perilesional edema.
