Cerebral Aneurysm Rupture Evaluation
The evaluation of a subarachnoid hemorrhage begins with a history and physical exam.
Although most patients with subarachnoid hemorrhage will have some findings on neurological examination, the physical exam may be normal. As many as 10% of patients with a history for a sudden-onset, severe and unusual headache, but a normal neurological examination, will have a subarachnoid hemorrhage.
Physical findings in someone with a subarachnoid hemorrhage may include:
- Numbness in one arm or leg:
- Weakness in one arm or leg:
- Facial weakness (unilateral):
- Difficulty swallowing
- Difficulty speaking
- Difficulty walking
- Difficulty with balance
- Loss of coordination
- Abnormal eye movements
- Abnormal pupils:
- Swelling in the back of the eye
- Memory problems
- Excessive sleepiness
Tests are necessary to make the diagnosis of a subarachnoid hemorrhage. The standard procedure for evaluating subarachnoid hemorrhage is neuroimaging (CT scanning of the brain) followed by lumbar puncture.
Tests that may be used to evaluate a subarachnoid hemorrhage include:
