Abstract
BACKGROUND Intraventricular meningioma (IVM) is a rare subtype of intracranial meningioma, accounting for 9.8 to 14% of all intraventricular tumors. Currently, there is no clear consensus on which patients with IVM should receive conservative treatment, surgery, or stereotactic radiosurgery (SRS). This research aims to analyze the outcomes, including survival and recurrence rates of patients who undergo SRS for IVM as a primary or adjuvant treatment. METHODS A systematic search was conducted in Scopus, Web of Science, PubMed, and Embase till June 5th 2023. Screening and data extraction were performed by two independent authors. Random-effect meta-analysis was performed to determine the tumor control proportion of IVM cases treated with SRS. Individual patient data (IPD) meta-analysis was performed for the progression-free survival (PFS) of the patients in the follow-up time. All analyses were performed using the R programming language. RESULTS Out of the overall 132 records, 14 were included in our study, of which only 7 had enough data for the meta-analysis. The tumor control proportion was 0.92 (95% CI, 0.69-0.98) in patients who underwent SRS for primary IVM. The overall tumor control in both primary and adjuvant cases was 0.87 (95% CI, 0.34-0.99). the heterogeneity was not significant in both meta-analyses (P = 0.73 and P = 0.92, respectively). Post-SRS perifocal edema occurred in 16 out of 71 cases (0.16; 95% CI, 0.03-0.56), with no significant heterogeneity (P = 0.32). IPD meta-analysis showed a PFS of 94.70% in a 2-year follow-up. Log-rank test showed better PFS in primary SRS compared to adjuvant SRS (P < 0.01). CONCLUSIONS According to this study, patients with IVM can achieve high rates of tumor control with a low risk of complications when treated with SRS, regardless of whether they have received prior treatment. Although SRS could be a promising first-line treatment option for asymptomatic IVM, its efficacy in symptomatic patients and its comparison with resection require further investigation.

Trapped temporal horn: From theory to practice, a systematic review of current understanding and future perspectives. World Neurosurg X 2024; 23:100345.

Abstract
Background The Entrapped Temporal Horn (ETH) is characterized by localized enlargement of the temporal horn of the lateral ventricle of the brain. This study aimed to investigate the factors, development, prognosis, and effective treatment. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, a systematic search was conducted in major research databases. The inclusion criteria included patients of all ages with TTH diagnosis in cohort studies, case series, and case reports. Results Our study included 160 patients and 49 studies. The major causes of TTH were neoplastic lesions (42.3%), infections (22.3%), and cystic disease (13.08%). Of these cases, 71 were unrelated to cranial surgery, while 89 were unrelated to prior surgeries. Headache was the most common symptom (41.91%), followed by seizures (13.20%), drowsiness (12.50%) and memory loss (11.00%). Surgery was not required in 17 patients. Fenestration of the trapped temporal horn was performed in 24 patients, while VP/VA shunt surgeries were performed in the majority (57 patients) owing to favorable outcomes, lower revision rates, and extensive experience. However, TTH recurred in six of the 21 patients who underwent endoscopic ventriculocisternostomy. Tumors were the main cause, and isolated headache was the most frequent symptom. Ventriculoperitoneal shunts (VPS) are preferred because of their positive outcomes, lower revision rates, and wider expertise. Tumors near the trigonal area pose a higher risk. Conclusion Although TTH remains a rare condition, VPS continues to be the most widely preferred procedure among surgeons.

Clin Neurol Neurosurg 2024; 244:108407.

Abstract
CONTEXT Entrapment of the temporal horn (TH) is rare condition that can lead to increased intracranial pressure, but there is no consensus on a standard treatment. The aim of this study was to conduct a systematic literature review of the reported cases of TH entrapment and describe our operative technique for endoscopic fenestrations of the lateral ventricle into the basal cisterns. METHODS We searched the databases Pubmed and Google scholar to find all studies reporting cases of entrapped TH and the subsequent treatment. Additionally, we report two illustrative cases of endoscopic fenestration with a step-by-step description of our surgical technique. RESULTS Twenty-nine studies with a total of 67 patients were included in the analysis. The mean age was 36.5 years (SD± 21.9), and the female-to-male ratio was 1.5. The most frequent cause of TH entrapment was post-surgical scarring after tumor surgery (n= 30), and the most commonly reported treatment modality was endoscopic fenestration of the TH (n = 14). We observed an increasing use of endoscopic fenestration over time. CONCLUSION Entrapped TH is a rare condition often requiring surgical treatment. Neuronavigation-guided endoscopic fenestration of the ventricle into the basal cisterns appears to be a safe, efficient, and device-free technique that has gained importance over the past years.

Abstract
Entrapment of the temporal horn (ETH) is a form of focal, obstructive hydrocephalus. Etiology and clinical presentation are diversified. Though known since 1947, standard treatment has not yet been defined. The objective of our study was to perform a systematic review on ETH. Data from patients treated at our Institution from 2008 to 2019 were retrospectively collected and analyzed. A systematic PRISMA review of literature was also performed using PubMed and Google Scholar. 121 cases (mean age 41 years; M/F ratio 1/1) were analyzed. In 65 (vs 56) cases (53.7% vs 46.3%) ETH was not surgery related. Headache was the most common symptom (42%). "Major" treatments were (1) ventriculoperitoneal/ventriculoatrial shunt (42 cases, 34.7%), and (2) endoscopic ventriculocisternostomy (12 cases, 9.9%). In the first group, no perioperative complications were found, 39 patients (92.9%) had a favorable outcome, 3 patients (7.1%) died for the underlying disease, 4 cases (9.5%) went through revision; also considering the cases in which another procedure was performed as definitive treatment, shunt failures were 6 (13.6%). In the second group, 1 case (8.3%) developed a deep intracerebral hemorrhage, 11 cases (91.6%) had a favorable long-term outcome, 1 case (8.3%) had a favorable short-term outcome; also considering the cases in which another procedure was performed as definitive treatment, endoscopic ventriculocisternostomy failures were 6 (37.5%). Described as uncommon, ETH is probably underestimated. Early diagnosis and appropriate treatment are critical. VP shunt is still the most commonly performed treatment. Further randomized clinical trials are, however, needed to establish the gold standard.
