Abstract
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.
