Subconjunctival fat prolapse - bilateral

Case contributed by Dr Angel Donato

Presentation

Fatty mass in the bilateral lateral canthal area.

Patient Data

Age: 80 years
Gender: Female

CT demonstrates prolapse fat at the superotemporal aspect of the bilateral epibulbar area continuous with the intraconal fat, lateral of the lacrimal gland.

Case Discussion

The principal imaging feature of subconjunctival fat prolapse is that the fatty mass is continuous with the intraconal fat. It's believed to be a herniation of intraconal fat due to a weakening of the Tenon capsule.

Subconjunctival fat prolapse and dermolipoma occur in the lateral canthal area of the temporal or superotemporal bulbar conjunctiva.
