Spontaneous thrombosis of a giant cerebral varix in a pediatric patient.

Introduction: Cerebral cortical venous aneurysm also known as cerebral varix is a rare entity that usually occurs in relation to high-flow draining veins of arteriovenous fistulas, arteriovenous malformations, and venous angioma. Isolated cerebral varix is an extremely rare entity.

Case Report: We present a 1-year-old male with isolated cerebral varix. During follow-up, the varix thrombosed spontaneously without causing any neurological deficits.

Conclusion: To the best of our knowledge, spontaneous asymptomatic thrombosis of an isolated cerebral varix without any clinical finding was reported for the first time in the literature.
