Abstract:
We studied MRI of 15 cases of arteriovenous malformation (AVM) with special reference on the coexistence of the subdural hematoma. All ruptured cases (6 cases) were associated with intracerebral hematoma, and half (3 cases) of them were coexisted with subdural hematoma. In one of them, the presence of the subdural hematoma promoted us to perform angiography which revealed the AVM.
Insights
Arteriovenous malformations (AVMs) can coexist with subdural hematomas. Subdural hematomas in ruptured AVM cases may indicate the need for further diagnostic imaging like angiography.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Context:
- Arteriovenous malformations (AVMs) are complex vascular anomalies.
- Subdural hematomas can occur secondary to various intracranial pathologies.
- The diagnostic challenges in identifying AVMs, especially when presenting with associated hemorrhages.
Purpose:
- To investigate the incidence and significance of subdural hematomas in patients with arteriovenous malformations.
- To evaluate the role of subdural hematomas as a potential indicator for AVM diagnosis.
- To analyze the relationship between ruptured AVMs, intracerebral hematomas, and subdural hematomas.
Summary:
- This study reviewed MRI scans of 15 arteriovenous malformation (AVM) cases.
- Six ruptured AVM cases were identified, all with associated intracerebral hematomas.
- Three of these ruptured cases also presented with subdural hematomas, prompting angiography in one instance, which confirmed the AVM.
Impact:
- Highlights the importance of considering subdural hematomas in the differential diagnosis of patients with suspected intracranial hemorrhage.
- Suggests that the presence of subdural hematoma in the context of intracerebral hemorrhage may warrant further investigation for underlying AVMs.
- Contributes to understanding the imaging features and diagnostic pathways for complex cerebrovascular lesions.
