Purpose:
To report the use of computed tomographic angiography (CTA) to diagnose an orbital varix.
Design:
Observational case report.
Methods:
A 73-year-old female was investigated by CTA for carotid artery stenosis. An incidental orbital lesion was discovered. Reformations were obtained.
Results:
CTA demonstrated a homogeneously enhancing orbital apex lesion. It provided exceptional anatomic detail of inflow and outflow veins, confirming the diagnosis of an orbital varix.
Conclusions:
CTA is cost effective, fast, non-invasive, and readily available. These aspects combined with the exceptional vascular detail obtained may make CTA the primary test for orbital varix diagnosis.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
