Аннотация
BACKGROUND: Rosette-forming glioneuronal tumor (RGNT) is a rare and distinctive glioneuronal tumor. Although surgical excision is considered the standard treatment for these slow growing WHO Grade I tumors, gross-total resection is achieved in less than 50% of RGNTs due to its localisation amidst vital structures. With very few cases with long term follow-up reported, there is limited knowledge of the natural clinical course and the role of radiotherapy in inoperable RGNTs.
CASE DESCRIPTION: A previously well 26-year old male, presented with long standing headache, increasing gait instability and fainting episodes. Imaging revealed a tectal plate mass with hydrocephalous. An endoscopic third ventriculostomy and biopsy was done, revealing RGNT. He received radiotherapy with a curative intent. The patient remained neurologically stable for 4 years. Follow-up imaging done after 4 years showed decrease in tumor size.
CONCLUSIONS: The current case highlights a role for radiotherapy in RGNTs occurring in surgically challenging sites.
