Intraoperative Visualization of Bilateral Thrombosis in the Posterior Inferior Cerebellar Artery Apparent in the Telovelomedullary Segment
Cranial MRI performed on day two after bilateral PICA infarct. Diffusion-weighted images (a)-(b) and diffusion coefficient maps (c)-(d) revealing fresh infarcts. The 3-dimensional time-of-flight magnetic resonance angiogram shows patency of both vertebral arteries, whereas absence of flow-related signal in both inferior posterior cerebellar arteries is demonstrated (e).
