Abstract:

Background.—Recent advances in ultrasound technology now allow the sonographer to obtain three-dimensional color power angiography (3D-CPA) vascular images and to enhance these images by rotation and subtraction. The purpose of this report is to demonstrate the sonographic presentation of a cerebral arteriovenous malformation (AVM) using these advanced techniques.

Patient.—During an emergency operation to evacuate a large subdural hematoma, the surgeon noted several aneurysmal veins, suggesting the presence of an underlying AVM. Angiography showed a compact AVM arising from a posterior temporal branch of the right posterior cerebral artery (PCA).

Findings.—Transcranial color Doppler ultrasonography (CDU) revealed an AVM in the right temporal lobe with a feeder arising from the P1 segment of the right PCA. 3D-CPA images of the AVM were then developed, rotated, and subtracted. These enhanced images provided superior definition of the arterial and venous architecture and were comparable to the angiogram.

Conclusion.—3D-CPA provided high-resolution, accurate, noninvasive images of a cerebral AVM. The added anatomic detail allowed by this technique was complementary to the hemodynamic information provided by CDU.
