Subarachnoid haemorrhage is a rare cause of headache and status epilepticus in children.

New onset of seizures in children presenting with status epilepticus (SE) are rarely caused by intracranial aneurysms and haemorrhage, and the diagnosis is therefore challenging. This case report presents a ten-year-old healthy girl presenting with SE preceded by headache for two weeks. A CT-scan showed a subarachnoidal haemorrhage from a cerebral aneurysm. Intracranial pathology should be considered a differential diagnosis when receiving a child with new onset of seizures and SE. Early neuroimaging should be performed for correct treatment to be initiated without delay.
