The Anterior Choroidal Artery Syndrome Neuroradiology 36:340-345, Takahashi,S.,et al, 1994 See this aricle in Pubmed Article Abstract We reviewed 12 cases of infarcts in the territory of the anterior choroidal artery(AChA)on CT and/or MRI.In each case vascular occlusion in the region was verified angiographically.Although the extent of the lesion on CT/MR images was variable,all were located on the axial images within an arcuate zone between the striatium anterolaterally and the thalamus posteromedially.The distribution of the lesions on multiplanar MRI conformed well to the territory of the AChA demonstrated microangiographically.The variability of the extent of the infarcts may be explained by variations in the degree of occlusive changes in the AChA or the development of collateral circulation through anastomoses between the AChA and the posterior communicating and posterior cerebral arteries.The extent of the lesion appeared to be closely related to the degree of neurological deficit.
