J Neurosurg Pediatr 2017 Nov 25;20(5):471-479. Epub 2017 Aug 25.

UCSF Benioff Children's Hospital Oakland, California.

Choroid plexus papillomas (CPPs) are typically benign tumors that can occur in any age group but are more commonly found in pediatric patients. Although these tumors are benign, there are several reports in adult patients of distant metastases present either at the time of diagnosis or occurring months to years after initial resection. Here, the authors report the case of a 14-year-old boy who presented with symptoms of elevated intracranial pressure due to obstructive hydrocephalus that was caused by a large fourth ventricular mass.

Third ventricular meningiomas.

J Clin Neurosci 2015 Nov 29;22(11):1776-84. Epub 2015 Aug 29.

Department of Medical, Laiwu Hospital, Taishan Medical University, Laiwu 271100, China.

We report 13 patients with third ventricular meningiomas (TVM) and discuss the clinical, radiological, pathological and surgical features, as well as follow-up of these tumors. TVM are rare intracranial tumors, and because of this, there are few reports in the literature. Of 11,600 intracranial meningiomas that were surgically treated and pathologically confirmed at Beijing Tian Tan Hospital over a period of 10 years (2003-2013), 13 TVM were selected for a retrospective review.

Embolization of a giant hypervascularized choroid plexus papilloma with onyx by direct puncture: a case report.

Childs Nerv Syst 2016 Apr 5;32(4):717-21. Epub 2015 Oct 5.

Neurosurgery Department, Neurological Institute of Curitiba (INC), Curitiba, Paraná, Brazil.

Background: Choroid plexus papilloma is a rare intracranial neoplasm derived from choroid plexus epithelium accounting for less than 1 % of all brain tumors. These tumors are highly vascularized, and tumor resection is difficult, especially in small children, due to severe intraoperative bleeding. Preoperative embolization is helpful to reduce intraoperative bleeding, but it may not be possible in small children or if the tumor has no suitable feeding vessels for embolization. Read More

DYSPHONIA AS AN UNCOMMON PRESENTATION OF PONTOCEREBELLAR CHOROID PLEXUS PAPILLOMA.

Acta Clin Croat 2015 Jun;54(2):227-31

A case is presented of a patient with dysphonia, hearing loss and ataxia due to vestibulocochlear and vagal nerve compression by choroid plexus papilloma in the cerebellopontine angle. Choroid plexus papillomas are rare tumors usually arising in the lateral and fourth ventricle, and rarely found in the cerebellopontine angle, making the neuroimaging characteristics usually not sufficient for diagnosis. Patients usually present with headache and hydrocephalus but tumors in the cerebellopontine angle can cause vestibulocochlear dysfunction and cerebellar symptoms. Read More

[Aicardi syndrome with Dandy-Walker type malformation].

Rev Neurol 2015 Jul;61(2):71-4

Universidad Industrial de Santander (UIS) - Facultad de Salud, Bucaramanga, Colombia.

Introduction: Aicardi syndrome (OMIM 304050) was first described in 1965. Its classic triad consists of infantile spasms, partial or total agenesis of the corpus callosum and ocular disorders, such as chorioretinal lacunae. It has been posited that it is due to a mechanism involving X-linked dominant inheritance. Read More

Pediatric choroid plexus papillomas and carcinomas are highly vascularized neoplasms, which are difficult to distinguish with conventional imaging. We aimed to analyze the diagnostic accuracy of PWI, by using both pseudocontinuous arterial spin-labeling and DSC-PWI. We reviewed the PWI of 13 children with choroid plexus neoplasms (7 papillomas and 6 carcinomas). Read More

Superior parietal lobule approach for choroid plexus papillomas without preoperative embolization in very young children.

J Neurosurg Pediatr 2015 Jul 10;16(1):101-6. Epub 2015 Apr 10.

Department of Neurological Surgery and.

OBJECT Choroid plexus papillomas (CPPs) are rare neoplasms, often found in the atrium of the lateral ventricle of infants, and cause overproduction hydrocephalus. The extensive vascularity and medially located blood supply of these tumors, coupled with the young age of the patients, can make prevention of blood loss challenging. Preoperative embolization has been advocated to reduce blood loss and prevent the need for transfusion, but this mandates radiation exposure and the additional risks of vessel injury and stroke.
