Cite this article as: A 54-year-old female patient was admitted to our outpatient clinic with a pulsatile mass and pain in the right side of her neck. Carotid Doppler ultrasonography revealed an aneurysm of the right internal carotid artery (ICA). Carotid artery angiography showed a right ICA aneurysm, measuring 3¥2 cm (Figure 1). Before surgery, multidetector computed tomography (MDCT) was performed to demonstrate the aneurysmal arterial segment and its connections with normal arterial structures. Multidetector computed tomography demonstrated multiple fusiform aneurysmal segments of both intracranial and extracranial carotid arteries, and aneurysms associated with arteriovenous malformations (AVMs) within the zone of circle of Willis (Figure 2). The patient was transferred to another hospital for further evaluation of definitive diagnosis and treatment.
