Hepatocellular carcinoma (HCC) with extrahepatic spreading is not uncommon. In order to delineate the clinical and radiological pictures of HCC with intracranial metastasis, 33 documented cases were analysed. Eighteen had brain parenchymal metastasis without skull involvement; the other 15 cases disclosed skull metastasis with brain invasion. The underlying HCC are mainly of expanding (13/33, 39.4%) and multifocal (13/33, 39.4%) types. Eighteen cases (18/33, 54.5%) had mental changes not related to hypoglycaemia or hepatic encephalopathy. Eighteen cases (18/20, 90%) disclosed hyperdense mass lesions by non‐contrast computed tomography (CT) scans and 17 cases showed homogeneous enhancement (17/22, 77.3%) by post‐contrast CT images. In the non‐skull involved group, five cases (5/12, 41.7%) disclosed ring‐shape enhancement and 14 cases (14/16, 87.5%) had perifocal oedema, which were not seen in the skull involved group. Eight cases (8/33, 24.2%) presented as intracerebral haemorrhage. Twelve (12/33, 36.4%) died of brain herniation. Most (14/18, 77.8%) non‐skull involved cases had simultaneous lung metastasis without bony metastasis, while the skull involved group often (10/15, 66.7%) disclosed extracranial bony metastasis without lung metastasis. The difference in extracranial metastasis was statistically significant ( P <0.05). The multivariate survival analysis disclosed that lower lactate dehydrogenase level (≤316 U/L, P = 0.029) and treatments (surgery or radiation, P = 0.001) were positively associated with longer survival. In conclusion, HCC with intracranial metastasis is symptomatic and life‐threatening. Half the cases may come from pulmonary metastasis and the other half may be from bony metastasis. Brain irradiation or surgery can prolong their survival.
