Bedside Iohexol Ventriculography for Patients with Obstructive Colloid Cysts: A Protocol to Identify Auto-Fenestration of the Septum Pellucidum.

World Neurosurg 2019 Feb 12;122:e279-e284. Epub 2018 Oct 12.

Department of Neurosurgery, Barrow Neurological Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, USA. Electronic address:

Objective: Patients with hydrocephalus secondary to third ventricular colloid cysts can require bilateral external ventricular drain (EVD) placement while awaiting surgery. However, some patients could develop auto-fenestration of the septum pellucidum (AFSP) and only require 1 EVD. We evaluated our experience with bedside iohexol ventriculography and staged EVD placement for patients with obstructive hydrocephalus. Read More

Endoscopic treatment of intraventricular ependymal cysts in children: personal experience and review of literature.

Childs Nerv Syst 2018 12 5;34(12):2441-2448. Epub 2018 Sep 5.

Department of Neurosurgery, Faculty of Medicine, Cairo University, 81 Nasr Road, Nasr City, Cairo, Egypt.

Object: Intracranial ependymal cysts are rare neuroepithelial cysts that occur less frequently than arachnoid cysts. The cysts are most often intraparenchymal, but they are rarely reported to be intraventricular. This study evaluates the role of endoscopy in the treatment of intraventricular ependymal cysts (IVECs). Read More

Fatal acute disseminated encephalomyelitis (ADEM) after third ventricle colloid cyst resection with ultrasonic aspirator during neuroendoscopic procedure.

Acta Neurochir (Wien) 2018 09 29;160(9):1789-1792. Epub 2018 Jul 29.

Service de Neurochirurgie, Hôpital d'Instruction des Armées Sainte Anne, BP600, 83800, Toulon Cedex 9, France.

We present the case of a patient who died of a fatal meningoencephalitis after removal of a third ventricle colloid cyst. Postoperative clinical and iconographic evolution let us think about an acute disseminated encephalomyelitis probably due to cerebrospinal fluid contamination by inflammatory proteins contained in the colloid cyst. This case raises the question of a possibility of colloid cyst content spraying while using an ultrasonic aspiration device. Read More

A unique finding of cavum velum interpositum colloid-like cyst and literature review of a commonplace lesion in an uncommon place.

Int J Gen Med 2018 16;11:301-305. Epub 2018 Jul 16.

Diagnostic Radiology Department, Dammam Central Hospital, Dammam, Eastern Province, Saudi Arabia.

Colloid cysts typically reside within the area of the anterior third ventricle, in the proximity of the foramen of Monro. Although they are considered to commonly localize in various parts of the cerebrum, they are exceedingly rare outside the ventricular system and rarely occur within the velum interpositum. We have reported here a rare case of a velum interpositum colloid-like cyst in a 23-year-old man, who presented to our clinic with temporary binocular strabismus, which he had been experiencing for the previous year.

Evaluation of Bremsstrahlung radiation dose in stereotactically radiocolloid therapy of cystic craniopharyngioma tumors with P radio-colloid.

Australas Phys Eng Sci Med 2018 Sep 9;41(3):697-711. Epub 2018 Jul 9.

Department of Neurosurgery, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Over 90% of craniopharyngeal brain tumors are cystic, which enables the injection of beta emitters such as phosphorus-32 (P) radio-colloid into cysts for their treatment. The aim of this study was to evaluate the clinical and theoretical modelling of Bremsstrahlung radiation dose resulting from stereotactic radio-colloid therapy of cystic craniopharyngioma tumors with P. P radio-colloid with appropriate activity concentration was injected to a head phantom, and then the Bremsstrahlung radiation spectrum and planar images were obtained using a gamma camera. Read More
