FIG 5. A 28-year-old woman with arteriovenous malformation in the left parietal lobe.

A, Sagittal T1-weighted image demonstrates an AVM in the parietal lobe and a hematoma in the splenium.

B, A left internal carotid artery angiogram, lateral view, reveals the AVM fed by anterior, middle and posterior cerebral arteries and drained into the vein of Galen.

C, 3D-CT angiography, superior view, showing a vascular malformation.

D-E, The 3D-CT arteriography (D) and 3D-CT venography (E), superior view, reveal the vessels on arterial-phase and venous-phase of the AVM, respectively.

F, The fused 3D-CT image, superior view, facilitates understanding of the anatomic relation of vascular structure between arterial-phase and venous-phase.
