Unilateral thrombosis of dominant internal jugular vein presenting with benign intracranial hypertension

Abstract

Idiopathic intracranial hypertension is defined as an elevation of intracranial pressure (ICP) with no identifiable aetiology. The term ‘pseudotumor cerebri’ or BIH, was commonly used in the past for idiopathic intracranial hypertension, but is now used to describe the chronic elevation of ICP regardless of its aetiology and is further divided into primary (idiopathic intracranial hypertension) and secondary forms. We report a rare case of BIH secondary to unilateral dominant internal jugular vein thrombosis.
