“…In the presence of local pathological factors, a direct surgical approach to remove an obstructive lesion is indicated for the treatment of hydrocephalus and ventricular diverticula [16]. If such an approach is not effective, however, ventricular shunting is probably the least dangerous and most effective method of treatment for uncomplicated diverticula, although endoscopic ventriculostomy may be indicated for selected patients [17].…”

Ventricular diverticula are dilatations of the ventricular system caused by stretching and protrusion of the ventricular wall as a result of severe chronic obstructive hydrocephalus. We report a case of lateral ventricular diverticulum arising from the occipital horn in a patient with occipital encephalocele. To the best of our knowledge, this is a first case of ventricular diverticulum in a patient with occipital encephalocele.

“…In another recent report, Abe et al [1] demonstrated clearly by cine MRI that the lateral ventricular diverticulum flows into the supracerebellar cistern near the antrum of the lateral ventricle. Based on these findings, they confirmed the herniation route of the lateral ventricular diverticulum through the medial antrum into the supracerebellar cistern.…”

“…A ventricular diverticulum has rarely been found in children or adults with long-standing severe obstructive hydrocephalus due to obstruction of the foramen of Monro, foramen of Magendi, and intra- or juxtaventricular tumors [1,2,3,4,5,6]. There have been few cases of infants reported in the past literature [7].…”

“…In 1982, Naidich et al [10] along with Sweet’s hypothesis postulated that the ventricular diverticulum of the lateral ventricle might develop from stretching and dehiscence of the fornix, resulting in separation of the fornix from the splenium. Recently, Abe et al [1] have suggested two classic routes, one between the splenium and the crus of the fornix, and another through the choroidal fissure as a medial wall of the antrum into the supracerebellar cistern.…”

A ventricular diverticulum is usually found in patients with long-standing severe obstructive hydrocephalus that may extend into the supracerebellar cistern. The route involved in the supracerebellar extension of the ventricular diverticulum is believed to originate through the tela choroidea of the temporal choroid plexus or of the antral choroid plexus. The authors report a 4-week-old girl with hydrocephalus as a result of unilateral obstruction of the foramen of Monro, which dilated the right ventricle and displaced the midline to the left side, collapsing the contralateral lateral ventricle. The dilated lateral ventricular diverticulum herniated to the supracerebellar cistern in the posterior fossa that compressed the cerebellum inferiorly. She was treated successfully by a ventriculoperitoneal shunt, resulting in a marked reduction of the ventricle and diverticulum on the follow-up computed tomography and magnetic resonance imaging. We reviewed the literature for the supracerebellar extension route of ventricular diverticulum and suggest that the medial choroidal fissure in the antrum and the velum interpositum may be important anatomical structures for the extension of the lateral ventricular diverticulum into the supracerebellar cistern.

“…Intraventricular diverticulum are extensions or focal outpouching of the ventricle lined by a prolapsed ependymal layer. [ 2 3 ] It occurs in the setting of longstanding hydrocephalus and resolves following treatment for hydrocephalus. The common causes include post neuroendoscopy, shunt placements, hemorrhage, and clinically silent focal ischemia.…”
