Intracranial extension |
| 1 | present | downward | partially enhancing infiltrative fat and soft tissue mass in right upper and lower lid—extension around globe. Later left lower lid swelling | normal | right all enlarged | increased density | normal | none | none |
| 2 | present | downward | enhancing soft tissue mass and fat in right upper lid with extension posterior to globe. Left lower lid swelling | normal | enlarged right superior rectus | normal | normal | none | none |
| 3 | present | none | right upper/lower preseptal soft tissue and fatty mass—posterior extension around globe | normal | enlarged right lateral rectus | normal | normal | none | none |
| 4 | present | downward | heterogeneous density right soft tissue mass with single high density fleck | encased superiorly | infiltration of right superior rectus | normal | normal | present | present |
| 5 | absent | none | bilateral soft tissue and increased fat in upper lids—extension into superior orbits | normal | early infiltration of superior recti | normal | bilateral enlargement | none | none |
| 6 | present | none | bilateral infiltrative soft tissue masses in upper lids with increased fat; calcified fleck in left mass | normal | enlarged superior recti and left lateral and medial recti | normal | left enlarged | none | none |
| 7 | present | downward | infiltrative right soft tissue mass | normal | enlarged right superior rectus | normal | right enlarged | none | none |
| 8 | present | none | right upper/lower preseptal soft tissue mass and prolapse of retrobulbar fat | normal | enlarged right superior and inferior recti | increased density | right enlarged | none | none |
| 9 | absent | none | right upper/lower preseptal soft tissue thickening | normal | enlarged right lateral rectus | normal | right enlarged | none | none |
