Summary
Cranial CT scans can diagnose iatrogenic cerebral air embolism. Initial CT scans may appear normal, but follow-up imaging is crucial for detecting infarcts in all patients.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Iatrogenic cerebral air embolism is a rare but serious complication.
- Prompt diagnosis is essential for patient management.
Observation:
- Cranial CT scans were performed on three patients with suspected iatrogenic cerebral air embolism within 24 hours of symptom onset.
- Initial CT findings varied, including a normal scan, a large enhancing lesion, and bi-thalamic infarction.
Findings:
- Follow-up CT scans 7-10 days later revealed single or multiple enhancing infarcts in all three patients.
- Computed tomography (CT) is a valuable diagnostic tool for cerebral air embolism.
Implications:
- While CT is useful, initial scans can be negative.
- Follow-up imaging is necessary to confirm diagnosis and assess the extent of brain injury.
