Abstract. The ventriculus terminalis is a cavity situated at the level of the conus medullaris, enclosed by ependymal tissue and normally present as a virtual cavity or as a mere ependymal residue. In rare cases, and almost exclusively in pediatric age, the ventriculus terminalis may be visualized by radiological investigations, either by sonography or MRI, and represents a transient finding in children under 5 years of age. In pathological conditions, a cyst of the conus medullaris is probably…

Cystic dilation of a ventriculus terminalis. Case report and review of the literature
TLDR
A 5 year-old-boy with a sphincteric and walking disorder and the presence of a cystic lesion containing cerebrospinal fluid, which did not enhance after gadolinium, compatible with the diagnosis of the ventriculus terminalis dilation is presented.
Surgery or not? A case of ventriculus terminalis in an adult patient.
TLDR
A case of an adult patient with a progressive dilatation of a diagnosed VT that is treated surgically is described and a management flowchart for this condition is proposed based on the experience and a review of the literature.
Cystic Dilation of the Conus Ventriculus Terminalis Presenting as an Acute Cauda Equina Syndrome Relieved by Decompression and Cyst Drainage: Case Report.
TLDR
Cystic dilation of the ventriculus terminalis should be part of the differential diagnosis for a cauda equina syndrome; surgical decompression with simple cyst drainage can result in excellent clinical results.
Cystic Dilation of the Conus Ventriculus Terminalis Presenting as an Acute Cauda Equina Syndrome Relieved by Decompression and Cyst Drainage: Case Report
TLDR
Cystic dilation of the ventriculus terminalis should be part of the differential diagnosis for a cauda equina syndrome; surgical decompression with simple cyst drainage can result in excellent clinical results.
Cystic lesion of the ventriculus terminalis: proposal for a new clinical classification.
TLDR
A new classification system is proposed in which the clinical presentation is taken into account to standardize the cases and facilitate the proper management of cystic lesion of the ventriculus terminalis in adults.
The cystic dilation of ventriculus terminalis with neurological symptoms: Three case reports and a literature review
TLDR
The cases of symptomatic fifth ventricle cystic dilations of the conus medullaris suggested that surgical decompression was a safe and effective treatment in symptomatic patients and the neurosurgeons should be aware of such rare situations.
Cystic dilation of the ventriculus terminalis.
TLDR
Surgical treatment seemed to guarantee the resolution of CDVT and a revision of the classification with subgroups Type Ia (nonspecific symptoms without clear relation to CDVT), which is best treated conservatively, and Type Ib (rapid onset and invalidating unspecific complaints without comorbidities), which may benefit from surgical evacuation.
The Slowly Enlarging Ventriculus Terminalis
TLDR
This, to the authors' knowledge, is the first described case of a slowly enlarging VT independent of any other imaging findings in a patient with progressing lower limb weakness without any history or imaging findings of trauma or spinal canal abnormalities.
Cystic dilation of the ventriculus terminalis in adults.
TLDR
The data suggest that the site, age, and histological characteristics of the lesion allow VT dilation as a nosological entity distinct from other cystic dilations of the conus medullaris to be defined.
MR imaging of ventriculus terminalis of the conus medullaris: A report of two operated patients and review of the literature
TLDR
2 patients in whom a cystic dilation of the conus medullaris was incidentally found at MR imaging carried out in the work-up for sciatica are reported on, avoiding surgery in a substantial number of cases.

Ventriculus terminalis of the conus medullaris: MR findings in children.
TLDR
Asymptomatic localized dilatation of the ventriculus terminalis is a normal developmental phenomenon that can be seen on MR.
Ventriculus terminalis of the conus medullaris: MR imaging in four patients with congenital dilatation.
TLDR
MR findings in four patients with MR evidence of congenital cystic dilatation of the ventriculus terminalis were reviewed retrospectively, and MR imaging shows no enhancement of the cyst or its wall, and thus differentiates congenital dilatations from cystic tumors, which occur more frequently in this region.
[History, controversy and pathogenesis].
TLDR
The historical and pathophysiological aspects of syringomyelia are discussed, including fluid cavities extending beyond several segments within the spinal cord this pathological entity is a condition with many possible causes and the origin of fluid cavity remain questionable.
Intramedullary cystic lesions of the conus medullaris.
TLDR
The cases of cysts of the conus medullaris reported here simulated the clinical picture of syringomyelia, tumour, or lumbar disc disease and the radiographic findings in each case were interpreted as indicating the presence ofan intramedullary tumour.
The ventriculus terminalis of the spinal cord in the neonate: a normal variant on sonography.
TLDR
The ventriculus terminalis is a normal anatomic variant of the conus medullaris that can be visualized on spinal sonograms in neonates that has remained asymptomatic during clinical follow-up periods of up to 2 years.

Terminal syringohydromyelia and occult spinal dysraphism.
TLDR
It is stressed that terminal syringohydromyelia is an important pathological entity that should be considered in patients with occult spinal dysraphism, and treated surgically when clinically or radiographically significant.
Terminal syringomyelia in association with the tethered cord syndrome.
TLDR
Radiologically significant terminal syringomyelia affects the clinical presentation of tethered cord syndrome, by increasing or inducing neurological deficits, and better clinical outcomes after syrinx decompression emphasize the importance of the recognition and treatment of this pathological condition.
Cystic dilatation of ventriculus terminalis in adults: MRI
TLDR
MRI findings in two patients with cystic dilatation of the ventriculus terminalis are reported, with the markedly dilated ventriculi terminalis seen as a rounded cavity with regular margins, the content of which gave the same signal as cerebrospinal fluid with all MR pulse sequences.
