Clinical features and imaging manifestations of retinoblastoma with hepatic metastasis.

Clinical data of five patients with hepatic metastases of retinoblastoma were analyzed retrospectively (two had bilateral tumors three had unilateral intraocular tumors). On computed tomography, multiple and single low-density foci were observed. Four patients had tumor remission, and one showed no response after chemotherapy. Three patients who underwent enucleation were at high risk for extensive choroidal invasion. Central nervous system and bone metastases occurred in all five patients. Neuron-specific enolase and lactate dehydrogenase levels were significantly elevated in all patients. Two patients died (not from hepatic metastasis). Three patients (one with tumor progression and two with shorter courses) are continuing treatment.
