Detection of subdural empyema with radionuclides
Clinical Nuclear Medicine
|June 1, 1980
Summary
Radionuclide brain scans can detect subdural empyema when computed tomography (CT) scans are normal. Indium-111 leukocyte scans also showed abnormal uptake in empyema cases, aiding diagnosis.
Area of Science:
- Neurology
- Radiology
- Nuclear Medicine
Background:
- Computed tomography (CT) is the standard for diagnosing subdural empyema.
- Subdural empyema diagnosis can be challenging, requiring sensitive imaging techniques.
Observation:
- A case presented with an abnormal radionuclide brain scan despite a normal CT scan.
- Indium-111 labeled leukocyte scintigraphy revealed abnormal uptake in the subdural empyema.
Findings:
- Radionuclide imaging, including Indium-111 leukocyte scans, can identify subdural empyema.
- Scintigraphy may offer diagnostic value when CT findings are equivocal or normal.
Implications:
- Radionuclide studies may complement CT in diagnosing subdural empyema.
- These findings suggest a potential role for nuclear medicine in challenging empyema cases.
