[Rathke cysts, craniopharyngioma, and colloid cysts : What are the differences between these pathologies?]

Authors:
R Eymann M Kiefer

Radiologe 2018 Jul;58(7):646-652

Universität des Saarlandes, Homburg/Saar, Deutschland.

Clinical Issue: Headache is the most common symptom of colloid cysts, Rathke cysts, and craniopharyngioma due to their location in the midline, being extra-axial and typically presenting in the parasellar region.

Therapeutic Problems: Although these tumors are generally considered benign, each has its typical characteristics defined by its location and histology. These individual characteristics define whether surgery is necessary at all and if so, the preferred surgical approach and resection's totality. Read More

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.

Microendoscopic Removal of Deep-Seated Brain Tumors Using Tubular Retraction System.

J Neurol Surg A Cent Eur Neurosurg 2016 Jul 11;77(4):312-20. Epub 2016 Apr 11.

Department of Neurosurgery, NSCB Medical College Jabalpur, Jabalpur, Madhya Pradesh, India.

Background Retraction of the overlying brain can be difficult without causing significant trauma when using traditional brain retractors with blades. These retractors may produce focal pressure and may result in brain contusion or infarction. Tubular retractors offer the advantage of low retracting pressure that is less likely to be traumatic.

Natural history of colloid cysts of the third ventricle.

J Neurosurg 2016 12 11;125(6):1420-1430. Epub 2016 Mar 11.

Department of Neurological Surgery and.

OBJECTIVE Colloid cysts are rare, histologically benign lesions that may result in obstructive hydrocephalus and death. Understanding the natural history of colloid cysts has been challenging given their low incidence and the small number of cases in most reported series. This has complicated efforts to establish reliable prognostic factors and surgical indications, particularly for asymptomatic patients with incidental lesions. Read More

Do tumor and ventricular volume predict the need for postresection shunting in colloid cyst patients?

J Neurosurg 2016 09 29;125(3):585-90. Epub 2016 Jan 29.

Department of Neurosurgery, University of Florida, Gainesville, Florida; and.

OBJECTIVE Many colloid cyst patients present with obstructive hydrocephalus that resolves after resection of the cyst. However, a proportion of patients with these cysts will require cerebrospinal fluid shunting after tumor resection, despite resolution of the obstruction at the foramina of Monro. The goal of this study was to determine if colloid cyst size or preoperative ventricular volume predicted the need for postresection shunting. Read More

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.

Pineal cyst resection in the absence of ventriculomegaly or Parinaud's syndrome: clinical outcomes and implications for patient selection.

J Neurosurg 2015 Aug 1;123(2):352-6. Epub 2015 May 1.

Centre for Minimally Invasive Neurosurgery, Prince of Wales Hospital, Sydney, New South Wales, Australia; and.

Object: Surgical indications for patients with pineal cysts are controversial. While the majority of patients harboring a pineal cyst require no treatment, surgery is a well-accepted option for a subset of those patients with secondary hydrocephalus or Parinaud's syndrome. The majority of pineal cysts are identified incidentally during workup for other potential conditions, which may or may not be related to the presence of the cyst. Read More

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

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
