title: Cerebellar infarction. Analysis of 22 cases.
abstract: Twenty-two cases of cerebellar infarction were diagnosed by clinical findings, computerized tomography (CT), magnetic resonance image (MRI) and autopsy. Most of the infarctions occurred in the territory of the posterior inferior cerebellar artery (18/22). The most common and earliest symptoms were dizziness or vertigo (19/22), which occurred repeatedly and were accompanied by nausea and vomiting. The symptoms and signs of cerebellar lesion such as unsteady gait, limb and/or trunk ataxia, dysarthria were also the main clinical manifestations. However, in a number of patients there were no cerebellar symptoms or signs (9/22). Rapid deterioration of consciousness suggested acute compression of the brainstem, where the prognosis would be poor. CT scan made it possible to diagnose cerebellar infarction in the patients. But CT is not a satisfactory instrument in identifying this disease. MRI without bony artifacts from the posterior fossa has much higher resolution and renders the infarction to be visualized earlier. It may be regarded as the most ideal instrument in diagnosing this disease.
