Comparative Analysis of Supratentorial Intraventricular Tumors in Adults and Pediatrics in a Developing Country: Clinicopathological Features, Surgical Management, and Outcomes

Abstract

Background Supratentorial intraventricular tumors, encompassing lateral and third ventricular tumors, are uncommon intracranial neoplasms, typically slow-growing and benign, manifesting symptoms only upon reaching a substantial size. This study aims to identify optimal surgical approaches, assess the prevalence and characteristics of these tumors, and evaluate postoperative outcomes among pediatric and adult age groups.

Methods A retrospective comparative study at a tertiary care hospital from January 2014 to June 2020 included 165 patients (68 pediatrics, 97 adults) meeting inclusion criteria for intraventricular tumor management. Data covered demographic factors, clinical history, neurological assessments, neuroimaging, surgical approaches, histopathological diagnoses, immunohistochemical features, adjuvant therapies, follow-up status, postoperative complications, and morbidity/mortality.

Results Ventricular tumor incidence showed male preponderance in both adults (M:F = 1.2:1) and pediatrics (M:F = 3:1). Lateral ventricles were the most common location. Pediatric cases exhibited more frequent calcifications on computed tomography scans (35.6% vs. 29.5%). Grade II and III tumors were more prevalent in adults within the lateral ventricle (27.1 and 1.9%) compared with pediatrics (6.5 and 8.4%). The third ventricle predominantly featured benign lesions, with pediatric patients experiencing significantly longer hospital stays (16.12 ± 21.94 days vs. 9.58 ± 6.21 days) (p = 0.006). Adults and pediatric patients showed a significant difference in high-grade lateral ventricle tumors (p-value = 0.002[*]).

Conclusions Supratentorial ventricular tumors are relatively more prevalent in children than adults, presenting challenges due to size and bleeding risks. Surgical resection is the primary treatment, with a focus on the optimal approach for gross total excision to reduce recurrence risk.
