“…Both entities have been identified on pneumoencephalography 1 or contrast ventriculography. 2,7,8,10,11,19 Magnetic resonance imaging is useful in their diagnosis and accurate anatomical definition. 14 Flow artifacts are evident on T2-weighted and FLAIR images; phase contrast cine MR imaging positively identifies CSF flow across the stoma.…”

Chronic obstructive hydrocephalus is known to cause ventricular diverticula and, rarely, spontaneous ventriculostomy. The authors present the case of a patient in whom a spontaneous third ventriculostomy was identified with long-standing hydrocephalus secondary to aqueductal stenosis. To their knowledge, this is the first report in which a spontaneous stoma in the floor of the third ventricle was evaluated using endoscopy and cerebrospinal fluid dynamics studies. Both studies confirmed that the spontaneous stoma is similar in structure and function to surgical third ventriculostomy.

“…21 All reported cases of STVs have been in the context of obstructive hydrocephalus and are thought to be associated with chronic increased ICP. 21,29,[32][33][34][35][36][37][38][39][40][41][42][43] The associated chronic increase in ICP leads to CSF pulsations pushing against the floor of the third ventricle, causing thinning and eventual rupture of the floor, thus relieving the increased ICP by CSF diversion into the subarachnoid space. 40,41 Although none of the 75 patients in our cohort demonstrated evidence of CSF flow obstruction, the 12 patients with STV were found to have a statistically significant increase in head circumference and ventricular volume in keeping with the diagnosis of hydrocephalus and increased ICP.…”

a b s t r a c tIntroduction: Spontaneous third ventriculostomies have been reported in relation to obstructive hydrocephalus and increased intracranial pressure and are most commonly seen as disruption of the floor of the third ventricle. Hydrocephalus has been reported in patients with Krabbe disease; however, it is clinically difficult to monitor for hydrocephalus in patients with Krabbe disease as symptoms of increased intracranial pressure may overlap with symptoms of Krabbe disease. We describe a case series of spontaneous third ventriculostomy and hydrocephalus, likely in response to increased intracranial pressure, in patients with infantile Krabbe disease. Methods: Brain magnetic resonance images of patients with infantile Krabbe disease were retrospectively analyzed to assess for ventricular size and presence of spontaneous third ventriculostomies. A brain atlas was used to standardize the calculation of ventricular size. Mid-sagittal, T2-weighted images around the third ventricle were assessed for spontaneous third ventriculostomies. Developmental outcomes were measured with a series of standardized and validated tests. Results: Seventy-five patients with infantile Krabbe disease were evaluated. Twelve cases of spontaneous third ventriculostomies were identified. Head circumference (SE ¼ 8.07; P < 0.001) and average ventricular volume were greater (left: SE ¼ 1.47, P < 0.001) in patients with spontaneous third ventriculostomies when compared with patients without spontaneous third ventriculostomies. Patients with spontaneous third ventriculostomies also had more delayed development in adaptive (difference ¼ 0.2, P < 0.01), gross motor (difference ¼ 0.0, P < 0.01), and fine motor (difference ¼ 0.1, P < 0.001) function. Conclusions: Spontaneous third ventriculostomies, likely in the context of increased intracranial pressure, were identified in patients with Krabbe disease. Although difficult to assess, our study highlights the importance of monitoring for increased intracranial pressure, which can result in spontaneous third ventriculostomies, in patients with infantile Krabbe disease.

“…Extending from each lateral ventricle were dorsolaterally directed channels, with the right channel reaching the surface of the brain, and serving as a conduit for CSF drainage into the subarachnoid space. Since this initial description, well-documented cases of spontaneous ventriculocisternostomies have been occasionally reported in the English literature, 2,3,[5][6][7][8][9][10][12][13][14]16 with only a few cases described in infants. 9,10,16 Spontaneous ventriculocisternostomy should be distinguished from ventriculum diverticulum, a distinct entity which can also occur in the setting of ventricular hypertension.…”

Spontaneous third ventriculocisternostomy in an infant with obstructive hydrocephalus

✓Spontaneous ventriculocisternostomy, the spontaneous communication between the ventricular system and the subarachnoid space, is rare. The authors report a case of an infant with obstructive hydrocephalus who developed a spontaneous third ventriculocisternostomy. The infant was initially evaluated for progressive ventriculomegaly and increasing head circumference (HC). During follow-up, the patient's HC began to follow percentile lines and magnetic resonance (MR) imaging demonstrated a reduction of the hydrocephalus. Flow-sensitive phase-contrast cine MR images revealed cerebrospinal fluid (CSF) flow through the floor of the third ventricle between the tuber cinereum and the mammillary bodies connecting the ventricular system with the prepontine cistern. Although rare, clinicians should be cognizant of this phenomenon as it may eliminate the need for CSF diversion.

Spontaneous rupture of the third ventricle in obstructive hydrocephalus: A radiographic diagnosis

Abstract: Two cases of posterior fossa tumours with spontaneous rupture of the third ventricle are presented. In the first case there was dramatic relief of symptoms of raised intracranial tension. Rupture of the supra-pineal recess was demonstrated by Conray ventriculography in both cases.
