Dural venous sinuses are large veins located in the brain that drain blood from the brain and direct it back to the heart. When lesions occur in these sinuses, it can lead to serious health issues. This guide will help you understand the different types of dural venous sinus lesions, their causes, symptoms, diagnostic methods, treatments (both non-pharmacological and pharmacological), surgical options, prevention strategies, and when to seek medical help.
