title: Computed tomographic patterns of intracranial infarcts in Ghanaians.
abstract: Computed tomography has given a boost to intracranial imaging in general, and the diagnosis of the subtypes of Cerebrovascular Accident (CVA) in particular. In this study of 1,172 cases of CVA examined by Computed Tomography (CT), 552 (47.10%) showed features of cerebral infarction. There was a male prevalence in the study and the mean age was 59.8 years. As in all infarcts the diagnostic appearance was a wedge shaped hypodensity within the brain parenchyma. This was most often found in the parietal lobe (73.6%) and was always without a mass effect. Even though solitary infarcts were frequent, multiple lesions were reported in 9.3% of cases and these group of respondents presented mostly with seizures. Diabetes mellitus was an important predisposing factor and was found in 163% of cases, while hypertension was found in only 9.1% of cases studied. Other CT findings were cerebral and cerebrellar atrophy. Calcification of the falx and the basal ganglia were also noted.
