Pseudotumour cerebri - Incidence, management and prevention

Benign or idiopathic intracranial hypertension, also termed 'pseudotumour cerebri', is defined by the presence of raised intracranial pressure (ICP) in the absence of a focal intracerebral space-occupying lesion. The signs and symptoms of elevated intracranial pressure are also observed such as headaches, nausea and vomiting, elevated arterial pressure and, often, bradycardia. Somnolence and palsy of the abducens nel ve are occasionally observed, while papilloedema causing reduction of visual acuity and blindness is a particularly defining feature.
