Overview
On ultrasound, retinoblastoma is characterized by echogenic soft-tissue masses with variable shadowing due to calcifications and heterogeneity due to necrosis and/or hemorrhage.[1]
Ultrasound
On ophthalmic B scan ultrasound, retinoblastomas appear as echogenic soft-tissue masses with variable shadowing due to calcifications and heterogeneity due to necrosis and/or haemorrhage. At diagnosis tumors are usually vascular on doppler examination. The vitreous may have multiple areas of 'floating' debris, which may represent vitreous seeding or alternatively necrotic debris, hemorrhage, or increased globulin content. On ophthalmic A scan ultrasound, retinoblastoma reveals variable or high internal reflectivity.[1]
