초록
“Artery of Percheron” is a solitary arterial trunk that arises from one of the proximal segments of a posterior cerebral artery and supplies the paramedian thalami and the rostral midbrain bilaterally. Occlusion of this trunk results in bilateral infarctions in the middle aspects of the thalami and brain stem. The clinical manifestations of this disease include the disturbances of consciousness, memory, eye movement, and behavior. We report two cases of bilateral paramedian thalamic infarcion demonstrated on diffusion weighted magnetic resonance (MR) images who showed different clinical manifestations.
