Idiopathic Precuneal Gyrus Herniation to Quadrigeminal Cistern by Flavio Ramalho Romero in Online Journal of Neurology and Brain Disorders in Lupine Publishers
Unlike brain herniation caused by mass effect due to trauma,tumor, infectious or inflammatory conditions, idiopathic brain herniation are extremely rare, with prevalence of 0,073% [1]. An
8 years-old girl who suffered a mild traumatic brain injury and
CT and MRI showed precuneal gyrus herniation to quadrigeminal
cistern. She was completely asymptomatic, without any finding of
high intracranial pressure (Figuire 1-2). Although it is a very rare
condition, is extremely important to recognize and differentiate
idiopathic brain herniations from other intracranial diseases such
as mass lesion, encephalocele or dural venous 'sinus thrombosis to
avoid excessive surgical and medical treatments [1-5].
