From: Dynamic evaluation of unruptured intracranial aneurysms by 4D-CT angiography: comparison with digital subtraction angiography (DSA) and surgical findings

Fig. 5

A-B CTA showed a right MCA-M1 aneurysm (1.5 mm x2.0 mm), and a tiny pulsation was observed by 4D-CTA (indicated by the white arrow). Both observers recorded the aneurysm as small, having no lobe, a wide neck, and clear visualization of parent and branch vessels. C DSA findings confirmed CTA findings. D-F photographs obtained during surgery, an abnormal thin wall of the aneurysm was observed during the surgery, i.e., there was a small protuberance, like a “bleeding blister”. The pulsation site displayed on CTA images colocalized with the relatively weak aneurysmal wall that is prone to rupture
