title: Arachnoid cyst resulting in sixth nerve palsy in a child.
abstract: A 2 year old presented with incomitant esotropia and abduction deficit consistent with sixth nerve palsy. Neuroimaging revealed an arachnoid cyst on the left. Neurosurgical shunting followed by strabismus surgery relieved the abduction deficit and esotropia. An arachnoid cyst may be a rare cause of acquired sixth nerve palsy and strabismus in children.
