Introduction
Retinoblastoma (RB) is the most common intraocular malignancy in infancy and childhood, with a reported incidence of one per 15,000–20,000 live births.1 RB accounts for 3% of all pediatric cancers.2 The overall survival rate of RB among children diagnosed early at the localized intraocular phase was reported to exceed 95%3, 4; however, delayed diagnosis and treatment, which are common in developing countries, may lead to extraocular metastasis, visual loss, and death. The sites of RB distant metastases include the central nervous system (CNS), bone, bone marrow, lymph nodes, and other organs5–9; hepatic metastases are rare. The objective of this study was to evaluate and summarize the clinical features, imaging manifestations, treatment, and prognosis of patients with RB having hepatic metastases.
