Abstract INTRODUCTION Central neurocytoma is the most common primary intra-ventricular tumor in adults being classified by the World Health Organization (WHO) as a benign grade II tumor with a good prognosis. Given the recent advances with regards to this tumor, a bibliometric analysis was due to study the change in research interest and patterns to identify the future direction of research for neurocytomas. MATERIALS AND METHODS A comprehensive Elsevier’s Scopus database search was performed to capture all published and indexed studies to date using the keywords "neurocytoma" and "central neurocytoma". A discrete set of validated bibliometric parameters were extracted and analyzed. All statistical analyses were performed on R 4.1.2. RESULTS A total of 1,002 documents were included in our analysis covering a period between 1910-2021 (111 years). Around 98.5% of the documents were multi-author publications with a collaboration index (CI) of 4.21. Acta Neuropathologica, The American Journal of Surgical Pathology, and Cancer were the journals to include the most number of top ten cited articles (2 out of 10 most cited articles, 20%). Switzerland (4 out of 10, 40%) accounted for the country to have the most number of top 10 most cited articles. The United States of America (5588 out of 16395 citations, 34.1%) had the most number of citations. Lastly, our analysis reported an annual growth rate of 6.9% for the number of papers produced by year. CONCLUSION This is the first bibliometric analysis to study the top 10 most cited articles with regard to neurocytomas. A shift from histopathologic and clinical symptoms toward treatment and management of the tumor was observed in our analysis. These findings highlight the need for investigation into treatment modalities for future research.
