“…Neurological examination is normal with the exception of unilateral or bilateral sixth nerve palsies, which occur in 9-48% of children (Wolf A et al, 2008;Rangwala LM et al, 2007 (Spennato P et al, 2011;Standridge SM, 2010) In children suspected of IIH, cranial imaging should be performed prior to LP to exclude a space occupying lesion in the brain. MRI is superior to computed tomography and the findings include tortuosity of the optic nerve, distension of perioptic subarachnoid space, posterior flattening of the globe or empty sella (Shin RK et al, 2001). CSF opening pressure of 25 mm Hg in children of 8 years or older, and opening pressure of 20 mm Hg in those younger than 8 years is diagnostic (Spennato P et al, 2011).…”
