Mandibular metastasis in hepatocellular carcinoma is rarely seen. Since the first case reported in 1957, only about 70 cases have been reported. To the best of our knowledge, only two cases presenting with acute haemorrhage episodes have been reported in the literature, despite the fact that hepatocellular carcinoma is a hypervascular tumour. Moreover, only one of the cases was managed with endovascular embolisation, which did not completely control the haemorrhage. We, hereby, present a case of a 65-year-old man with known hepatocellular carcinoma with metastasis to the mandible complicated by uncontrollable haemorrhage from the tumour, which was effectively controlled by endovascular embolisation. Angiographic anatomy and endovascular treatment of this rare site of metastasis are also illustrated.

血管內栓塞術治療肝細胞癌下頜骨轉移灶的出血併發症

肝細胞癌轉移至下頜很罕見。自從1957年的首宗病例到現時為止，只有約70個病例報告。儘管肝細胞癌屬於富血管性腫瘤，但據我們所知，文獻中亦只有兩例有急性出血的情況。而且其中一例雖以血管內栓塞術治療，但都不能完全控制出血。本文在此報告一名65歲肝細胞癌男性病例，癌細胞轉移至下頜，轉移瘤無法控制出血，最終以血管內栓塞術有效地控制出血。本文亦討論了這種罕見部位轉移瘤的血管造影解剖和血管內介入治療。
