    Description
    This B-mode transverse ultrasound scan shows asteroid hyalosis with partial posterior vitreous detachment. A dome-shaped choroidal melanoma is observed in the inferior quadrant (preequatorial to equatorial region), appearing as a solid, regularly bordered lesion with heterogeneous internal structure and mild acoustic attenuation. Standardized A-mode reveals medium-to-low internal reflectivity. The tumor measures 11.62 mm in base diameter and 6.60 mm in height. The retina and choroid remain attached, with minimal suprachoroidal fluid in the inferior quadrant.
