BACKGROUND Hepatocellular carcinoma (HCC) with right ventricle metastasis without inferior vena cava and right atrium involvement is very rare and the prognosis of HCC with RV metastasis is generally poor. The mass in the cardiac chamber may lead to lethal instability of hemodynamics, however, the initial symptom is probably non-specific, which means that diagnosis timely becomes even harder. CASE PRESENTATION We present a 63-year-old male with isolated metastasis of HCC in the right ventricle which caused inflow obstruction. Moreover, we reviewed a series of studies of isolated metastasis of hepatocellular carcinoma between 1980 and 2018, and summarized the relative outcomes. CONCLUSIONS Isolated metastasis of hepatocellular carcinoma in the right ventricle is extraordinarily rare. It may damage cardiac structure and broke hemodynamic balance. Multimodality imaging plays an important in accurate pre-operation assessment. Nowadays, palliative treatments could relieve fatal symptoms to some degree, however, standard treatment has not been well established.

右心室肝细胞癌的孤立转移。

背景技术具有右心室转移而无下腔静脉和右心房受累的肝细胞癌（HCC）非常罕见，并且伴有RV转移的HCC的预后通常较差。心腔内的肿物可能导致血液动力学的致命性不稳定，但是，最初的症状可能是非特异性的，这意味着及时的诊断变得更加困难。病例介绍我们介绍了一位63岁的男性，其右心室有孤立的HCC转移，导致流入阻塞。此外，我们回顾了1980年至2018年间进行的一系列孤立的肝细胞癌转移研究，并总结了相关结局。结论右心室肝细胞癌的孤立转移极为罕见。它可能会破坏心脏结构并破坏血液动力学平衡。多模态成像在准确的术前评估中起着重要的作用。如今，姑息治疗可以在某种程度上缓解致命症状，但是标准治疗尚不完善。
