We describe 3 cases of brain metastases in patients suffering from post-HBV hepatocarcinoma. The ＂stroke-like＂ presentation of the cerebral localization of the disease can be explained by both the important vascularization of the tumor and the frequent hemocoagulative alterations caused by the cirrhosis. The importance of diagnostic neuroradiology is briefly addressed, with reference to the fundamental role played by MRI. Surgery of these lesions does not present any particular technical problems as long as they are located in accessible areas and the patient＇s general and neurological conditions allow it. Postoperative radiotherapy seems to improve the quality and quantity of residual life, although the number of patients described in the literature was too small to draw any definite conclusion in this regard.展开更多
