Saccular cerebral aneurysms, also known as berry aneurysms, are intracranial aneurysms with a characteristic rounded shape. The wall of the artery is weak in these aneurysms, which means that under certain conditions, like high blood pressure (hypertension), the vessel wall can break and allow blood to flow into the subarachnoid space between the arachnoid mater and pia mater. When the abnormality has been confirmed to be vascular, the differential includes: Regardless of the modality used, a number of features need to be assessed to allow a decision in relation to treatment to be made: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.
