title: Early ultrasonographic diagnosis of hereditary retinoblastoma.
abstract: A hereditary retinoblastoma (RTB) was identified by ocular echography in a newborn, whose predisposition to RTB had been assessed based on the family history and DNA testing of the chorionic villi at the eighth week of pregnancy. Ultrasonography was performed during pregnancies without an abnormality being demonstrated. On the third day of life a B-scan examination showed a small membranous lesion in the nasal parapapillary area, whilst on A-scan, the lesion appeared as a hyperreflective peak. Thanks to its early identification, the tumor was successfully treated by photocoagulation.
