Abstract
We report a case of diffuse arteriovenous malformation (AVM) in basal ganglia and an internal capsule associated with venous aneurysms. The patient was treated by embolization guided by CT angiography to target the basal ganglionic portion of the AVM while sparing the internal capsule. Our case demonstrates that it is possible to obtain good quality intranidal angiograms by using CT angiography, which can be useful for exact localization of the catheterized part of the nidus.
Highlights
Anew combined angiography/CT suite has been developed that uses flat-panel detector technology for higher-resolution angiography that is capable of producing conebeam volume CT.[1,2,3,4]

The CTA was useful for anatomic localization of the nidal components, which would have been difficult to determine only by the angiographic criteria
Summary
Anew combined angiography/CT suite has been developed that uses flat-panel detector technology for higher-resolution angiography that is capable of producing conebeam volume CT.[1,2,3,4] We report a case of diffuse arteriovenous malformation (AVM) in basal ganglia and an internal capsule treated by targeted embolization guided by CT angiography (CTA). The technique enabled us to perform precise targeted embolization of the desired nidal components so as to decrease the risk of serious neurologic injury in our case of diffuse AVM involving vital structures.
