[Cerebellar infarction; the findings of CT, MRI and cerebral angiography].
The findings of CT, MRI and cerebral angiography were analysed in 18 cases with cerebellar infarction, of which 10 were men and 8 women. The areas of infarction were as follows; PICA in 9 cases, SCA in 8 cases, AICA and diffuse type in one case each. One case had two lesions. CT showed low density areas in 15 cases after 24 hours of the onset, but an abnormality was not demonstrated in one case which had an infarction of PICA area. MRI showed a high-intensity lesion on T2 weighted image during the first and tenth day after the onset, while a low-intensity lesion on T1 weighted image and high-intensity lesion on T2 weighted image were demonstrated after seventh day. MRI revealed the area of infarction better than CT. Vertebral angiography and DSA showed narrowing or poor visualization of the cerebellar arteries in 5 cases but this finding was not shown in 3 cases which were examined by IVDSA.
