Comparison of clinical and neuroradiological findings in first-ever stroke. A population-based study

Lindgren, Arne LU ; Norrving, Bo LU ; Rudling, O and Johansson, Barbro LU (1994) In Stroke: a journal of cerebral circulation 25(7). p.1371-1377
Abstract
BACKGROUND AND PURPOSE: To determine how a recently proposed clinical stroke subclassification corresponds to specific findings on computed tomography (CT) and magnetic resonance imaging (MRI) of the brain. METHODS: Two hundred twenty-eight patients with first-ever stroke were divided into four clinical subgroups: (1) total anterior circulation syndrome: both cortical and subcortical symptoms from anterior and middle cerebral artery territory; (2) partial anterior circulation syndrome: more restricted and predominantly cortical symptoms from the same arterial territories; (3) lacunar syndrome; and (4) posterior circulation syndrome: vertebrobasilar or posterior cerebral artery symptoms. The imaging protocol included CT of the brain on day... (More)
BACKGROUND AND PURPOSE: To determine how a recently proposed clinical stroke subclassification corresponds to specific findings on computed tomography (CT) and magnetic resonance imaging (MRI) of the brain. METHODS: Two hundred twenty-eight patients with first-ever stroke were divided into four clinical subgroups: (1) total anterior circulation syndrome: both cortical and subcortical symptoms from anterior and middle cerebral artery territory; (2) partial anterior circulation syndrome: more restricted and predominantly cortical symptoms from the same arterial territories; (3) lacunar syndrome; and (4) posterior circulation syndrome: vertebrobasilar or posterior cerebral artery symptoms. The imaging protocol included CT of the brain on day 0 through 15 and a second CT and an MRI of the brain on day 16 through 180 after acute stroke onset. RESULTS: There were 200 patients with cerebral infarction and 28 patients with intracerebral hemorrhage. Intracerebral hemorrhage was found in 19% of patients with total anterior circulation syndrome and in no patients with lacunar syndrome (chi 2 test; P < .01 for the difference between the four clinical subgroups). Of the 200 patients with cerebral infarction, 27% had total anterior circulation, 30% partial anterior circulation, 26% lacunar, and 16% posterior circulation syndromes. CT within 2 days revealed a visible lesion in about two thirds of patients with infarctions of total or partial anterior circulation syndrome type, compared with only 22% of patients with lacunar infarction (chi 2 test; P = .02 for the difference between the four subgroups). The mean volume of the symptomatic infarction on CT within 15 days was 95 mL for total anterior circulation, 20 mL for partial anterior circulation, and 2.5 mL for lacunar syndrome (one-factor ANOVA; P = .0001). A cortical involvement of the infarction on CT day 16 through 180 was seen in 81% of patients with total anterior circulation syndrome and 58% of those with partial anterior circulation syndrome, compared with only 8% of patients with lacunar syndrome (chi 2 test; P = .0001). MRI more often than CT showed a cortical involvement of lacunar infarctions and also revealed more silent lesions. CONCLUSIONS: The described clinical subgroups significantly differed in frequencies of intracerebral hemorrhage, cortical involvement, and lesion volume on CT and MRI. (Less)
