Evaluation of a rare case of orbital venous varix with multiple intracranial venous malformations using prone MRI technique

Orbit is a common site for vascular lesions in all age groups, with venous malformations being the most common type. Orbital varices are a rare subset of venous malformation which is a vascular hamartoma that communicate with normal orbital veins. The mainstay of diagnosis and differentiation from other vascular and neoplastic lesions of orbit is demonstration of change in size of lesion on dynamic maneuvers. In this article, we present a case of left orbital venous varix which showed enlargement on Valsalva maneuver. The patient was evaluated using prone MRI technique to demonstrate increase in the size of lesion. Multiple asymptomatic developmental venous anomalies were detected on brain screening, which is a known association.
