Summary
Air in epidural hematomas is uncommon but can occur without fractures. This study discusses seven cases and the significance of air within epidural hematomas, even without clear CT scan evidence of fracture.
Area of Science:
- Neurosurgery
- Radiology
- Trauma Management
Background:
- Air within an epidural hematoma is an infrequent radiological finding.
- This finding is typically associated with fractures involving cranial air sinuses.
- However, air can be present without any detectable fracture on computed tomography (CT) scans.
Purpose of the Study:
- To describe seven cases of epidural hematoma with intraparenchymal air.
- To discuss the clinical significance and potential etiologies of this uncommon finding.
- To evaluate the association between air in epidural hematomas and cranial fractures.
Main Methods:
- Retrospective review of seven cases with epidural hematoma and intraparenchymal air.
- Analysis of CT scans to identify associated fractures, particularly of air sinuses.
- Clinical data review for patient outcomes and management.
Main Results:
- Seven cases of epidural hematoma containing air were identified.
- In some cases, air was present without evidence of fracture on CT.
- The significance of air in epidural hematomas, regardless of fracture, was evaluated.
Conclusions:
- Air in epidural hematomas is an uncommon finding that warrants careful consideration.
- The presence of air may occur even without demonstrable fractures on CT imaging.
- Further investigation into the implications of air in epidural hematomas is necessary.
