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

Acquired Chiari I Malformation with Syringomyelia Secondary to Colloid Cyst with Hydrocephalus-Case Report and Review of Literature.

World Neurosurg 2017 Dec 9;108:995.e1-995.e4. Epub 2017 Sep 9.

Department of Neurosurgery, NRI Academy of Sciences, Chinakakani, Mangalagiri, Guntur, Andhra Pradesh, India.

Introduction: Acquired Chiari malformation and associated syringomyelia have been previously described following lumbar puncture/drainage, lumboperitoneal shunts, and spontaneous cerebrospinal fluid leakage. In addition to these etiologies, space-occupying lesions such as meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are rare causes of acquired Chiari malformation and syringomyelia. We report a rare case of colloid cyst with hydrocephalus causing secondary Chiari malformation with syringomyelia. Read More

Spontaneous resolution of colloid cyst of the third ventricle: Implications for management.

Asian J Neurosurg 2017 Apr-Jun;12(2):203-206

Division of Neurosurgery, Toronto Western Hospital, Toronto, Ontario, Canada.

While there is little controversy regarding the treatment of symptomatic colloid cysts, the optimal management of "incidentally" detected and asymptomatic colloid cyst remains unclear. The age of the patient, duration and significance of symptoms related to the cyst, size and radiological characteristics of the cyst and the presence of hydrocephalus are all factors to be considered before considering surgery. While surgery most often provides good results in the majority of patients, complications do occur. Read More

Endoscopic Reconstruction of CSF Pathways in Ventricular Tumors.

Acta Neurochir Suppl 2017 ;124:89-92

Neurosurgical Department, Regina Elena National Cancer Institute, Via Elio Chianesi 53, Rome, 00144, Italy.

Neuroendoscopy is now considered to be a minimally invasive surgical approach for expanding lesions bulging into the ventricle, and it is also considered to be a relevant tool for performing biopsy procedures, fenestration of cystic walls, or for performing tumor removal in selected cases. Furthermore, the use of neuroimaging and the accurate follow-up of brain tumor patients have allowed the documentation of tumoral and pseudotumoral cystic areas that cause the obstruction of cerebrospinal fluid (CSF) pathways. Neuroendoscopic procedures enable the fenestration of cystic lesions, in addition to enabling third ventriculostomy or septostomy to restore CSF pathways. Read More

A multiport MR-compatible neuroendoscope: spanning the gap between rigid and flexible scopes.

Neurosurg Focus 2016 Sep;41(3):E13

Department of Cardiovascular Surgery, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts.

OBJECTIVE Rigid endoscopes enable minimally invasive access to the ventricular system; however, the operative field is limited to the instrument tip, necessitating rotation of the entire instrument and causing consequent tissue compression while reaching around corners. Although flexible endoscopes offer tip steerability to address this limitation, they are more difficult to control and provide fewer and smaller working channels. A middle ground between these instruments-a rigid endoscope that possesses multiple instrument ports (for example, one at the tip and one on the side)-is proposed in this article, and a prototype device is evaluated in the context of a third ventricular colloid cyst resection combined with septostomy.

Neuropsychiatric Manifestations of Colloid Cysts: a review of the literature.

Psychiatr Danub 2015 Sep;27 Suppl 1:S315-20

Cambridge University Hospitals NHS Foundation Trust, Cambridge Biomedical Campus, Hills Road, Cambridge, CB2 0QQ, United Kingdom.

Colloid cysts account for approximately 2% of primary brain tumours and the majority of cases are identified in the fourth and fifth decade. They are small, gelatinous neoplasms lined by a single layer of mucin-secreting columnar epithelium that are thought to arise from errors in folding of the primitive neuroepithelium. They develop in the rostral aspect of the third ventricle in the foramen of Monro in 99% of cases and despite their benign histology carry a poor prognosis, with a mortality greater than 10% in symptomatic cases.

Neurosurgical management of a giant colloid cyst with atypical clinical and radiological presentation.

J Neurosurg 2014 Nov 22;121(5):1185-8. Epub 2014 Aug 22.

Departments of Medical Imaging.

The finding of a colloid cyst on neuroimaging is often incidental. These lesions are usually located at the foramen of Monro, are hyperdense on CT scans, and generally demonstrate signal intensity of water on MR images, although this depends on their content. When symptomatic, they frequently present with headaches and nausea due to an obstructive hydrocephalus. Read More

BMJ Case Rep 2014 Jul 21;2014. Epub 2014 Jul 21.

Departments of Neurosurgery and Radiology, Medical University of South Carolina, Charleston, South Carolina, USA.

A patient presented with headaches and was found to have a colloid cyst in the third ventricle and ventriculomegaly. The patient underwent endoscopic colloid cyst resection and third ventriculostomy without incidence. Prior to emergence, a blown right pupil was acutely noted, and bright red blood emanated from the ventricular drain that was routinely placed in the endoscopy tract at the conclusion of the procedure.

Endoscopic transtubular resection of a colloid cyst.

Neurosciences (Riyadh) 2014 Jan;19(1):43-6

Department of Neurosurgery, Stanford University, Stanford, California, United States of America.

Colloid cysts, benign outgrowths from the roof of the third ventricle, warrant resection when they become symptomatic. Historically, this has been performed by craniotomy and a transcortical or a transcallosal approach that employs a pair of fixed blade retractors and an operating microscope. Less invasive endoscopic techniques have employed rigid endoscopes with single or dual working channels. Read More

Patient-specific dosimetry for intracavitary 32P-chromic phosphate colloid therapy of cystic brain tumours.

Eur J Nucl Med Mol Imaging 2013 Oct 6;40(10):1532-41. Epub 2013 Jun 6.

Joint Department of Physics, Institute of Cancer Research, Sutton, London, SM2 5NG, UK,

Purpose: (32)P-chromic phosphate colloid treatments of astrocytoma and craniopharyngioma cystic brain tumours in paediatric patients are conventionally based on a sphere model under the assumption of uniform uptake. The aims of this study were to determine the distribution of the absorbed dose delivered by (32)P on a patient-specific basis and to evaluate the accuracy with which this can be predicted from a pretherapy administration of (99m)Tc-Sn colloid.

Methods: Three patients were treated with (32)P-chromic phosphate colloid following (99m)Tc-Sn colloid administrations. Read More

Neurosurg Focus 2013 Jan;34(1 Suppl):Video 7

Goodman Campbell Brain and Spine, Indiana University Department of Neurological Surgery, Indianapolis, Indiana 46202, USA.

Anterior third ventricular lesions present with a variety of symptoms related to cerebrospinal fluid flow obstruction and mass effect. Colloid cysts are among the most common lesions in the region. They usually present with ventriculomegaly, leading to headaches, vertigo, or, rarely, decreased mental status due to the development of acute hydrocephalus. Read More

Thunderclap headache: diagnostic considerations and neuroimaging features.

Clin Radiol 2013 Mar 11;68(3):e101-13. Epub 2012 Dec 11.

Department of Neuroradiology, Frenchay Hospital, Bristol, UK.

Thunderclap headache (TCH) is an acute and severe headache that has maximum intensity at onset; TCH can be primary or secondary. Primary TCH is diagnosed when no underlying cause is discovered; however, imaging is crucial in distinguishing secondary causes, which are wide-ranging. The radiologist should be aware of the list of potential diagnoses. Read More

Large hemorrhagic colloid cyst in a 35-year-old male.

Turk Neurosurg 2012 ;22(6):783-4

University Hospital Zagreb, Department of Radiology, Zagreb, Croatia.

Colloid cysts are rare benign tumors of the third ventricle with diverse clinical presentation, which vary from incidentally found cysts to acute death. An uncommon hemorrhage in these cysts is a life threatening complication which can cause obstructive hydrocephalus with acute deterioration of the patient and sudden death. We present a case of 35-year-old man with large hemorrhagic colloid cyst of a third ventricle causing acute obstructive hydrocephalus even though magnetic resonance image with low T2 signal of the cyst suggested its clinically stable nature.

Nephrogenic systemic fibrosis in the podiatric patient.

J Am Podiatr Med Assoc 2012 Sep-Oct;102(5):419-21

East Valley Foot and Ankle Specialists, Mesa, AZ, USA.

Nephrogenic systemic fibrosis (NSF) is a severely debilitating disease that was first described in the literature by Cowper and colleagues in 2000. It is pertinent to the field of podiatry because patients with NSF first manifest cutaneous symptoms in the lower extremity in the form of fibrosing lesions. To date, these lesions have been documented only in people with moderate to severe kidney failure. Read More

Colloid cyst of the third ventricle associated with anterior cerebral artery trifurcation and agenesis of the corpus callosum: findings on MRI and CT angiography.

Pediatr Radiol 2012 Sep 18;42(9):1130-3. Epub 2012 Apr 18.

Radiology Department, Izmir Tepecik Training and Research Hospital, Izmir, Turkey.

We report MRI with diffusion-weighted imaging, and multidetector CT angiography findings in a child with complete agenesis of the corpus callosum associated with a colloid cyst and trifurcation of the anterior cerebral artery. Although rare, a colloid cyst should be considered in the differential diagnosis of midline lesions in children with agenesis of the corpus callosum since it may require surgical intervention.

Endoneurosurgical resection of intraventricular and intraparenchymal lesions using the port technique.

World Neurosurg 2013 Feb 10;79(2 Suppl):S18.e1-8. Epub 2012 Feb 10.

Brain Tumor Center & Pituitary Disorders Program, John Wayne Cancer Institute at Saint John's Health Center, Santa Monica, California, USA.

Objective: Deep-seated intraventricular and intraparenchymal lesions have traditionally been resected via transcortical routes, often requiring the use of retractors to maintain the corridor created to reach the lesion and proceed with a bimanual microsurgical resection. A transparent cylindrical conduit (port) has been developed to resect deep-seated lesions using the endoscope or, more recently, Video Telescopic Operating Microscopy (VTOM) for visualization. We describe the surgical technique of the port technique and discuss the evolution of the concept of intraaxial brain surgery performed through a conduit. Read More
