Background/Aims: Different tectal masses have been described; most are low-grade gliomas. Only 20-30% of all lesions grow, as shown on follow-up MRIs, requiring surgical resection at some point. The aim of this study is to describe the experience of a single institution managing pediatric patients with tectal lesions. Methods: We retrospectively studied and analyzed 40 children with tectal lesions managed from 1990 to 2006; the mean age at diagnosis was 9.4 years. A volumetric classification was used to analyze tumor growth trends. More than 1 year of imaging follow-up was available for 23 patients. Results and Conclusion: Medium- and large-volume-size lesions were associated with the need for surgery. About half of the nonsurgical lesions grew at least 50% over a period of 4.5 years and did not require surgical resection.

“…Tectal glioma is a glioma that arises in the midbrain and is rare in adults. 4 It is a benign tumor that occurs mainly in children. A high seizure prevalence rate of 12.1% (8 of 66) has been reported; however, 50% were seizures not related to the tumor, such as febrile seizure, meningitis, and postoperative sequelae, and tectal glioma was discovered inciden-tally during the seizure evaluation in 25% of the patients.…”

Tectal glioma is an indolent and benign tumor that occurs predominantly in the pediatric population. It arises in the tectum of the midbrain and, due to its location, contributes to the development of obstructive hydrocephalus, typically presenting with increased intracranial pressure (IICP) symptoms or signs. Here we report a rare case of tectal glioma that presented as adult-onset epileptic seizures without IICP symptoms and was treated with endoscopic third ventriculostomy and antiepileptic drugs.

“…Conservative management involving CSF diversion and no surgical biopsy or resection of tectal lesions has been the favoured approach when such lesions demonstrate characteristic imaging findings of low-grade tumor, indolent growth, and the absence of progressive neurological deficit. 5 While focal tectal and tegmental midbrain lesions may have a benign clinical course, there is still a risk for tumor growth or transformation to higher grade necessitating continued surveillance after surgical intervention to relieve obstructive hydrocephalus. In a series of seven patients under the age of 25, increase in tumor size was observed in six patients and the magnitude of increase in size ranged from 1.6 to 3.8 times the original size.…”

By reviewing our experience in this patient population we sought to ascertain the degree of symptom improvement with ETV and the risk of treatment failure as defined by the need for ventriculoperitoneal shunting.…”

476The development of neuroendoscopic techniques for the management of obstructive hydrocephalus has provided an alternative to shunt systems for cerebrospinal fluid (CSF) diversion. Endoscopic third ventriculostomy (ETV), pioneered by Mixter in 1923 and later Vries, 1 involves the use of a transmitted light source in the form of a flexible or rigid endoscope to visualize the intraventricular spaces of the lateral and third ventricle. This permits the positioning of blunt instruments or a coagulating laser for the creation of an opening in the tuber cinereum. Such an opening allows the free flow of cerebrospinal fluid generated in the lateral and third ventricles directly into the basal subarachnoid space, obviating passage through the aqueduct of Sylvius and the fourth ventricle. The most common application of ETV has been in the setting of obstructive hydrocephalus to provide for a physiologic correction of hydrocephalus 2 potentially avoiding the complications of ventriculoperitoneal shunting such as recurrent ABSTRACT: Background: Tectal gliomas commonly present with hydrocephalus from obstruction of the aqueduct of Sylvius. The creation of a ventriculostomy in the floor of the third ventricle (ETV) has been previously reported to by-pass aqueduct obstruction. The goal of this study was to determine the safety and efficacy of ETV in the presence of an obstructing tectal glioma. Methods: We retrospectively reviewed the clinical presentation, management, and clinical outcome after ETV in patients diagnosed with tectal glioma and obstructive hydrocephalus in our institution over a period of 15 years. Shunt freedom at follow-up was the main outcome variable. Long-term clinical outcome was assessed at the most recent clinic visit. Clinical outcome was ranked as excellent, good, or poor according to resolution of symptoms and patient functional status. Results: The median age at presentation was 16.5 years (range: 6.4 to 59 years) and the most common presenting symptom was headache. Eleven patients had ETV as a primary procedure and three patients underwent ETV as a substitute for shunt revision at the time of shunt failure. At follow-up (median 3.9 years, range: 2.2 to 7 years) 13 of 14 patients remain shunt independent with excellent (n=9) or good outcomes (n=5). Conclusions: In patients with tectal glioma causing obstructive hydrocephalus, ETV can be performed safely in the primary setting or as a substitute for shunt revision. A high rate of shunt freedom (78%-100%) at prolonged follow-up can be expected in this patient population.RÉSUMÉ: Ventriculostomie du troisième ventricule par voie endoscopique pour une hydrocéphalie due à un gliome tectal. Contexte : Les patients atteints de gliomes tectaux présentent souvent une hydrocéphalie due à une obstruction de l'aqueduc de Sylvius. Selon des études antérieures, la création d'une ventriculostomie dans le plancher du troisième ventricule (ETV) contourne l'obstruction de l'aqueduc.
