소뇌경색증은 전체 뇌경색 중에서 비교적 적은 비율을 차지하는 질환이나 환자의 생명을 위협할 수도 있기 때문에 정확한 진단이 필요하다. 저자들은 본 연구에서 소뇌경색증 40예의 임상증상, 신경학적 징후를 알아보고 위험 인자, 혈관 구역, 경색의 크기 등을 조사하고 환자의 예후에 영향을 끼치는 요인들에 대해서 분석하였다. 소뇌경색증의 가장 흔한 증상과 징후는 현훈, 구토, 체간 및 사지 실조였으며 증상, 징후와 예후는 혈관 구역에 따라 차이가 없었다. 경색의 크기가 클 때, 심인성 색전이 존재할 때 그리고 내원 당시의 의식이 나쁠 때 소뇌경색증 환자의 예후가 좋지 않았다. Objective : Cerebellar infarction is not common but it can give vital influence on the neighboring structures. Therefore, it is important to make correct diagnosis and know general clinical features including prognosis. We performed this study to explore the full spectrum of the clinical characteristics, neurologic signs, vascular territories, prognosis and neuroimaging findings of cerebellar infarction. Methods : We retrospectively studied 40 patients with cerebellar infarction diagnosed by computed topography and/or magnetic resonance imaging who admitted during 5 years. Results : The background and risk factors were similar to those wish infarctions of the cerebral hemispheres. The embolic infarctions were 37.5%. Infarcts involving the superior cerebellar artery (SCA) region and the posterior inferior cerebellar artery (PICA) region were far more frequent than those involving the anterior inferior cerebellar artery (AICA) region. The most common and earliest symptoms were dizziness or vertigo. The symptoms and signs of cerebellar lesion such as unsteady gait, limb and/or trunk ataxia were also the main clinical manifestations. Conclusion : These findings indicate similar frequencies of SCA and PICA territory infarcts and illustrate some differences in clinical presentation but do not illustrate the differences in outcomes between SCA and PICA infarcts. They also indicate that not only in situ thrombosis but also cardiogenic embolism play important roles in the pathogenesis of cerebellar infarction. The factors affecting the prognosis are size of infarction, the presence of cardiogenic embolism and consciousness disturbance.
