What causes subarachnoid hematoma?

A subarachnoid hematoma is primarily caused by the rupture of blood vessels in the subarachnoid space, often due to head trauma or the rupture of an aneurysm. Other potential causes include arteriovenous malformations and certain bleeding disorders. The accumulation of blood can lead to increased intracranial pressure and neurological complications. Prompt medical intervention is crucial for managing the condition and minimizing potential damage.
