Bilateral Central Retinal Vein Occlusion in Recurrent Frontal Lobe Tumor.

Systemic malignancy can induce hypercoagulation and can cause retinal vein occlusion (RVO). Although RVO has been reported in association with breast, renal, lung, prostate, and ovarian malignancies, it has not been reported in brain tumors. We are reporting a case of bilateral central retinal vein occlusion (CRVO) associated with recurrent frontal lobe gliosarcoma. The association was established after ruling out all other systemic causes that can produce bilateral CRVO. The importance of this case report lies in the fact that, while evaluating bilateral CRVO cases, these rare associations should also be kept in mind.
