title: Orbital varix diagnosed by color Doppler flow imaging--case report.
abstract: A 66-year-old male presented with an angiographically occult orbital varix. Angiography and phlebography failed to demonstrate the lesion. Computed tomography angiography showed the varix, but not the vascular flow. Color Doppler flow imaging clearly demonstrated the well-defined varix with slow flow velocity, as well as the precise anatomical location. We recommend color Doppler flow imaging as one of the differential diagnostic tools for intraorbital vascular lesions.
