Non-contrast CT shows the presence of a hyperdense tubular mass within the right parietal lobe with dilated extra-axial vessels. No acute intracranial hemorrhage or cerebral edema noted. The ventricular system is not dilatated.
The arterial phase confirms the suspicion of a dilatated vessel.

Delayed CT shows the nidus of malformation with arterial supplying branch and dilated draining vein.
Case Discussion
Example of a cerebral arteriovenous malformation, suspected on the non-contrast CT brain scan confirmed on post-contrast imaging.
Cerebral arteriovenous malformation is a common form of cerebral vascular malformation and consists of a nest of vessels through which arteriovenous shunting occurs.
