Rapid Deterioration and Fatal Outcomes in Colloid Cyst-Induced Obstructive Hydrocephalus: A Case Report.

Colloid cysts are rare intracranial tumors that can cause obstructive hydrocephalus, a potentially life-threatening condition. Despite being typically benign, they often present with insidious symptoms, leading to delayed diagnosis and catastrophic outcomes. A 29-year-old woman presented with a two-month history of worsening headaches, nausea, and vomiting.

Endoscopic Bimanual Resection of Recurrent Colloid Cyst.

Colloid cysts are nonneoplastic epithelial lesions arising from the roof of the third ventricle near the foramen of Monro. They comprise approximately 0.5% to 2% of all brain lesions.

Ventricular Migration of Vitreous Silicone Oil Masquerading as a Ruptured Colloid Cyst.

The ventricular migration of vitreous silicone oil (SiO) is rare and can easily be mistaken for intraventricular hemorrhage or a ruptured colloid cyst. We report here the case of an adult male who was misdiagnosed with a ruptured colloid cyst and was subsequently found to have ventricular migration of vitreous SiO. A 57-year-old male presented unresponsive following a respiratory arrest and underwent a head computed tomography (CT) scan that demonstrated multiple ovoid hyperdensities in the ventricular system, which was concerning for a ruptured colloid cyst.

Imaging of supratentorial intraventricular masses in children: a pictorial review-part 2.

Purpose: This article is the second in a two-part series aimed at exploring the spectrum of supratentorial intraventricular masses in children. In particular, this part delves into masses originating from cells of the ventricular lining, those within the septum pellucidum, and brain parenchyma cells extending into the ventricles. The aim of this series is to offer a comprehensive understanding of these supratentorial intraventricular masses, encompassing their primary clinical findings and histological definitions.

Acute hydrocephalus caused by colloid cyst of third ventricle: A case report.

Colloid cysts (CCs) of third ventricle are rare benign lesions. They present with acute hydrocephalus and its sequalae like brain herniation, infarcts resulting even death in otherwise healthy individual. We present a case of an acute hydrocephalus caused by CC of third ventricle.

Isolated Intraventricular Neurocysticercosis: Atypical Presentation of a Colloid Cyst.

Neurocysticercosis is a condition characterized by the presence of Taenia solium (larval stage: Cysticercus cellulosae) in the brain and is classified as a tropical disease. Although it was previously uncommon in Europe, the number of cases has been increasing over the past decade. In this report, we present a case of a patient who was admitted with symptoms of raised intracranial pressure and biventricular hydrocephalus, without evidence of infection.

Endoscopic ultrasonic aspirator-assisted removal of a third ventricular colloid cyst.

Background: Colloid cysts are benign tumors usually located on the roof of the third ventricle. Cyst removal is the treatment of choice. It can be accomplished microsurgically through a transcortical- or transcallosal approach, or endoscopically.

Endoscopic trans-septal interforniceal approach for excision of colloid cysts of the third ventricle using the rotational technique.

Colloid cysts of the third ventricle are benign intracranial lesions that account for 0.5 to 2% of all brain tumors and are even rarer in pediatric population. Dandy was the first to successfully excise a colloid cyst of the third ventricle via a transcortical transventricular approach in 1921.

Behavioral disinhibition following corpus callosotomy done for colloid cyst excision in 15-year-old girl: A case report and literature review.

Background: There is a growing body of literature suggesting that the corpus callosum plays an important role in behavior. While behavioral deficits are a rare complication following callosotomy, they are well-documented in agenesis of the corpus callosum (AgCC), with emerging evidence reporting disinhibition among children with AgCC.

Case Description: A 15-year-old girl had undergone a right frontal craniotomy and excision of a third ventricle colloid cyst using the transcallosal approach.

Endoscopic resection of a giant colloid cyst in the velum interpositum: illustrative case.

Background: Colloid cysts are an unusual differential diagnosis for lesions in the lateral ventricles. Microsurgery is usually recommended for the treatment of giant colloid cysts. This case is the largest reported colloid cyst in this unusual location treated with an endoscope.

On Natural History and Management of Colloid Cysts: Time to Rethink?

Background: Colloid cysts, although benign, may occasionally cause obstructive hydrocephalus and sudden death. Reliable prognostic factors for symptomatic progression have been sought, with heterogenous results.

Methods: We conducted a retrospective review of all cases of colloid cysts of the third ventricle managed at our center between 2009 and 2019.

Structural Brain Network Reorganization Following Anterior Callosotomy for Colloid Cysts: Connectometry and Graph Analysis Results.

Introduction: The plasticity of the neural circuits after injuries has been extensively investigated over the last decades. Transcallosal microsurgery for lesions affecting the third ventricle offers an interesting opportunity to investigate the whole-brain white matter reorganization occurring after a selective resection of the genu of the corpus callosum (CC).

Method: Diffusion MRI (dMRI) data and neuropsychological testing were collected pre- and postoperatively in six patients with colloid cysts, surgically treated with a transcallosal-transgenual approach.

Impaired recollection and initially preserved familiarity in a patient with bilateral fornix transection following third ventricle colloid cyst removal: A two-year follow-up study.

Objective: Recognition memory is widely accepted as a dual process-based model, namely familiarity and recollection. However, the location of their specific neurobiological substrates remains unclear. Similar to hippocampal damage, fornix damage has been associated with recollection memory but not familiarity memory deficits.

Giant Colloid Cyst.

Giant colloid cysts are defined as cysts of more than 3 cm in maximal diameter. Few cases of giant colloid cysts have been reported in the literature. We herein describe a giant colloid cyst.

Xanthogranulomatous Colloid Cyst in a 13-Year-Old Boy: A Case Report and Surgical Implications.

Introduction: Colloid cysts are relatively uncommon lesions in the pediatric population. The xanthogranulomatous (XG) variant is very rare with less than 30 reported cases.

Case Report: In this report, the patient was a 13-year-old boy who presented with transient episodes of headache with blurring of vision.

Familial colloid cysts: not a chance occurrence.

Purpose: Colloid cysts are rare, benign brain tumors of the third ventricle with an estimated population prevalence of 1 in 5800. Sudden deterioration and death secondary to obstructive hydrocephalus are well-described presentations in patients with a colloid cyst. Although historically conceptualized as driven by sporadic genetic events, a growing body of literature supports the possibility of an inherited predisposition.

[Microscopic excision of a colloyd cyst of the third ventricle assisted by endoscopy. Case report and literature analysis.].

Introduction: Colloid cysts are histologically benign lesions, probably derived from the endoderm, which represent 0.3-2% of brain tumors. They are usually attached to the roof of the third ventricle in direct relation to the foramen of Monro, which can cause a blockage to the circulation of cerebrospinal fluid, determining hydrocephalus and in some cases sudden death.

Retrospective evaluation of endoscopic treatment in colloid cyst of the third ventricle.

Introduction: Endoscopic methods have gained a well-established position in surgical treatment of colloid cysts of third ventricle. However, the possibility of total tumor removal with this method and the long-term effectiveness of treatment are being questioned.

Aim: Personal twenty years' experience in treatment of third ventricle colloid cysts is presented on the basis of retrospective analysis.

Perspectives on Endoscopic Transseptal Interforniceal Approach for Retroforaminal Colloid Cysts.

Background: Although the interforniceal approach with the preservation of the fornix is useful during the endoscopic approach for retroforaminal colloid cysts, it carries a significant risk of memory and cognitive difficulties. Because most reports have reported the endoscopic approach to colloid cysts through the foramen with little emphasis on retroforaminal cysts, the aim of this study was to investigate colloid cysts as a special entity with regard to their different characteristics and surgical approaches and outcomes.

Methods: In this retrospective study, 12 patients with third ventricular colloid cysts with retroforaminal extensions were included.

The black rim susceptibility sign in the MRI evaluation of intracranial colloid cysts.

Background And Purpose: Colloid cysts are relatively rare intracranial lesions located in the rostral aspect of third ventricle. They may produce acute hydrocephalus, brain herniation, and death. On conventional MRI, the appearance of a colloid cyst varies depending on its composition.

Single Burr-Hole Extended Transforaminal Approach for Concurrent Endoscopic Surgery in the Third Ventricle Posterior to the Foramen of Monro and Ventriculostomy: Clinical Series and Planning Steps.

Objective: For endoscopic surgery of third ventricular lesions posterior to the foramen of Monro that frequently require a third ventriculostomy during the same procedure, the extended transforaminal approach (ETFA) through the choroid fissure has been proposed. This study reports clinical results and provides anatomic background and guidelines for individual planning of a single burr-hole approach and a safe transchoroid entry zone.

Methods: A retrospective review was undertaken of 25 cases of concurrent third ventricle surgery and third ventriculostomy via ETFA.
