"Non-contrast orbital scans may demonstrate phleboliths. Contrast should be administered during the Valsalva phase. The varix will appear as an irregular or smooth enhancing lesion which significantly increases in size with straining, typically located at the orbital apex 2. Enhancement should match that of other venous structures (e.g. cavernous sinus)."
"It should be noted that there is confusion and controversy in the literature as to the precise definitions of orbital vascular malformation with a venous component (e.g. varix, lymphangioma, venous malformation)."
