The causes of sixth nerve palsies in 75 children, all of whom had undergone
modern neuroimaging, were reviewed, Neoplasms or their neurosurgical remov
al was the most common cause (n = 34 [45%]); elevated intracranial pressure
(nontumor) (15%), traumatic (12%), congenital (11%), inflammatory (7%), mi
scellaneous (5%), and idiopathic (5%) causes represented other categories b
ut were less commonly present. Isolated sixth nerve palsies were relatively
uncommon (9%), On the basis of the relatively high risk of neoplasm, the a
uthors suggest neuroimaging early in the clinical course of children with s
ixth nerve palsies, even if the palsy is isolated, (C) 1999 by Elsevier Sci
