- Description
- This B-mode transverse ultrasound scan reveals a mushroom-shaped choroidal tumor in the inferior nasal quadrant adjacent to the optic nerve head. The lesion appears solid with homogeneous internal reflectivity and is associated with minimal surrounding subretinal fluid and scleral excavation. It measures 6.54 mm in height × 7.52 mm in base diameter (transverse view) and extends 9.52 mm longitudinally. The vitreous contains abundant punctate opacities consistent with pigment dispersion. The retina and choroid remain attached elsewhere.
