    Abstract:
    Of 598 consecutive non-selected cases of cerebral infarction included in a stroke registry, 82 cases (54 men and 28 women, mean age 66 +/- 14 years) of spontaneous and isolated posterior cerebral artery (PCA) territory infarction (right PCA in 36, left PCA in 35 and both in 11) were identified on the basis of CT combined with MRI in 51 cases. Infarction was superficial in 25 (group A), combined deep-superficial in 23 (group B) and deep in 34 (group C). Of 48 superficial lesions, 29 were massive while 19 were restricted to the territory of one branch. Of 57 deep lesions, 21 were located in the inferolateral thalamic territory, 10 in the paramedian thalamic territory, 12 in other midbrain or thalamic territories, and 14 in a combination of various midbrain and/or thalamic territories. Of 41 patients with unilateral superficial involvement, 39 had homonymous visual field defect. Unawareness of the visual defect and visual release hallucinations were observed with the same frequency in right and left lesions. Of 7 patients with bilateral superficial involvement, only 5 had bilateral visual field defect including incomplete cortical blindness in 3. The frequency of confusional state (n = 24) did not differ significantly in left versus right sided lesions while it was significantly higher in superficial or combined versus deep lesions (p = 0.05). Of 18 clinically evaluable patients with left PCA territory infarct, 14 had speech disorders including pure alexia in only one case. Of 15 patients with right territory infarction, 10 had spatial judgement disorders.(ABSTRACT TRUNCATED AT 250 WORDS)
