The diagnosis of intracranial dissecting aneurysms needs particular caution because aneurysm sac thrombosis can give false reassurance on angiographic MR sequences. Moreover, the anatomic features of intracranial artery walls make them prone to sub-adventitial dissection and subsequent subarachnoid haemorrhages. Therefore, antithrombotic therapy should be used with caution, due to the risk of bleeding in these intracranial dissections.
