Application of intraoperative ultrasonography in space-occupying cerebellar lesions GUO Zhi-xiang, HE Wen,

Objective To discuss the clinical value of the intraoperative ultrasonography in space-occupying cerebellar lesions. Methods Forty-one patients with space-occupying cerebellar lesions were collected to perform intraoperative ultrasonography, including 12 glioma, 10 hemangioblastoma, 10 arteriovenous malformations (AVM) ,4 metastatic carcinoma,3 angioeavernoma, 1 meningeoma and 1 paraganglioma. The location,depth, size, there were 16 nodes in 10 hemangioblastoma,and intraoperative ultrasonography found 14 of them. The rest space-ultrasonography showed a good correspondence in the degree of resection with postoperative CT or MRI. Conclusions Intraoperative ultrasonography could display clearly the location, size and boundary of cerebellar lesions, guide exactly the approach to resect the lesions in real time, it is of great value in cerebellar occupying lesions resection.
