A case of a cerebellar (vermian) hematoma that communicated with the fourth ventricle as seen on air study is presented. Although vertebral angiography appears to be the first diagnostic procedure of choice, the angiographic study may not be definitive diagnostically because it may be difficult to distinguish fourth ventricular enlargement from a cystic hematoma cavity in communication with the fourth ventricle. An air study may then be required to differentiate between such diagnostic possibilities.
本文报告一例小脑（蚓部）血肿病例，气脑造影显示该血肿与第四脑室相通。尽管椎动脉血管造影似乎是首选的诊断方法，但血管造影检查在诊断上可能并不明确，因为可能难以区分第四脑室扩大与与第四脑室相通的囊性血肿腔。此时可能需要进行气脑造影以区分这些诊断可能性。
