Cerebral arteriovenous malformation

Case contributed by Dr Henry Knipe


Transient left facial droop.

Patient Data

Age: 25 years
Gender: Female

Hyperdense tubular mass within the right frontal lobe with dilated extra-axial vessels. No acute intracranial hemorrhage nor cerebral edema. Normal ventricular size. 

Right frontal arteriovenous malformation with the nidus measuring 15 x 36 mm (AP x ML). The feeding arterial supply are superior M2 division branches of the right middle cerebral artery. There is also an asymmetrically enlarged right PCOM with a normal right P1 segment suggesting possible arterial supply via the vertebrobasilar system. Early filling of dilated superficial cortical veins on the right, which in turn drain into the right cavernous sinus as well as the superior sagittal sinus. No evidence of drainage to deep cerebral veins.

Case Discussion

Example of a large cerebral arteriovenous malformation, the diagnosis is highly suspicious on the non-contrast CT brain and confirmed on post-contrast imaging.
