A rare tumor in the sellar region: ganglioglioma, a case report and a general overview

Background Gangliogliomas are rare mixed neuronal-glial tumors of the central nervous system, accounting for less than 2% of intracranial tumors. Case description This report presents a rare case of ganglioglioma in the sellar region of a 3-year-old and 5-month-old pediatric patient. The patient underwent surgical intervention initially through a transnasal transsphenoidal approach and subsequently through a transcranial pterional craniotomy approach. Subsequently, radiotherapy and chemotherapy were administered for residual tumor tissue. The purpose of this report is to highlight the presence of ganglioglioma as a distinct diagnosis in sellar region tumors, discuss the surgical, radiotherapy, and/or chemotherapy treatment options for sellar region gangliogliomas based on the literature, and contribute the patient’s follow-up and treatment outcomes to the existing literature. Conclusion Complete tumor resection may not be feasible in sellar region gangliogliomas, especially in pediatric cases, due to endocrinological and vision-related complications. In cases where complete resection is not possible, radiotherapy and/or chemotherapy may be considered. However, the optimal treatment approach has not yet been established, and further research is needed.
