Abnormal protrusion of the globes bilaterally.
On axial CT images and at a level of the lens , the distance from the anterior margin of the globe to interzygomatic line should not exceed 21 mm. If this distance exceeds 21 mm, it is compatible with proptosis 2.
In this case the distance from the anterior margin of the globe to the line is 23 mm on the right side and 25 mm onde the left side. The findings are comptible with ocular proptosis due to thyroid ophthalmopathy.
