Background: Diffuse leptomeningeal glioneuronal tumor (DLGNT) was recently added to the World Health Organization classification of central nervous system tumors. DLGNT is a rare entity that occurs more commonly in pediatric patients, but occasional cases have been reported in adults. This tumor has been recognized as a distinct pathologic entity; however, its biologic behavior remains unclear. It is considered an indolent neoplasm, although considerable morbidity has been reported. For this reason, further characterization and collection of evidence are crucial. Methods: In this article, we reported a case of a 36-year-old woman with a DLGNT characterized by rapid, aggressive behavior. We also performed a review of the literature for reported cases of low-grade and high-grade forms involving adults and children. Results: DLGNTs should no longer be considered only as low-grade tumors affecting pediatric patients. The spectrum of presentations also includes aggressive tumors affecting adults. Conclusions: Further clinical and pathologic data supported by cytogenetic and molecular investigations are mandatory to better characterize DLGNTs.
