Within the intraconal right orbit superolateral to the optic nerve is a homogenously enhancing, microlobulated, circumscribed mass.

Decreased size of the orbital mass
Case Discussion
The mass spontaneously decreased in size on subsequent CT. The mass again enlarged on a third CT obtained later (not shown).
The fluctuating size of the mass documented by CT is diagnostic of a venous malformation. The same can be elicited by repeating CT during valsalva manoeuvre to increase venous pressure.
