文摘

Discrimination of intramural hematoma from intra-aneurysmal blood flow is a critical issue for determining the necessity of treatment in vertebral artery dissection (VAD) cases. We describe modified four-dimensional computed tomographic angiography (4D-CTA) that is useful for evaluating blood flow in a dissected vertebral artery in a 41-year-old man who was diagnosed as VAD. Magnetic resonance angiography (MRA) showed a growth of intramural hematoma, which was confusingly similar to intra-aneurysmal blood flow. Modified 4D-CTA enabled us to discriminate the intramural hematoma from blood flow because of its fine time and spatial resolution. Modified 4D-CTA may be a substitute for angiography in VAD cases.
