Overview
On ultrasound imaging, retinoblastoma is characterized by echogenic soft-tissue masses with variable shadowing due to calcification and heterogeneity due to necrosis and/or hemorrhage.
Ultrasound
- Ultrasound B-scan is helpful in the primary method to confirm the presence of a mass in the eyeball.[1]
- This imaging method is useful in:
- Measuring the dimensions of mass
- Detecting associated vitreous seeds or retinal detachment
- Excluding optic nerve invasion
- On ultrasound imaging, retinoblastoma appears as:
- A dome-shaped solid mass with variable internal reflectivity.
- Intralesional calcification may or may not be seen.
- The accuracy of this imaging study in diagnosing retinoblastoma has been observed to be between 87.5% to 100%.[2][3]
