title: Intraventricular haemorrhage without subarachnoid haemorrhage due to a ruptured aneurysm.
abstract: The incidence of aneurysmal subarachnoid haemorrhage (SAH) in the UK is about 10 per 100 000 of the population per year and it is a potentially fatal condition. Prompt recognition and referral to a neurosurgical unit is crucial for a better outcome. A typical history of sudden severe headache, CT scan and sometimes a lumbar puncture would help clinch the diagnosis. Though intracerebral haemorrhage (ICH) and intraventricular haemorrhage (IVH) are not uncommon after an aneurysmal rupture, ICH and/or IVH without SAH are rare (<2%). In such cases, a high index of suspicion is needed to deliver the correct management. This report describes a case of posterior communicating artery aneurysm presenting with pure IVH on CT. The aneurysm was diagnosed by performing a CT angiogram and the patient underwent a successful coil embolisation.
