Abstract

Diffuse leptomeningeal glioneuronal tumor (DLGNT) is an entity introduced in 2016 World Health Organization classification of tumors of the central nervous system. The tumor occurs very rarely. Due to the lack of specific clinical and radiological features, biopsy is necessary to be performed and histological and immunohistochemical testing is essential to reach the diagnosis. A 4.5-year-old girl presented with a history of headache, vomiting, and right eye convergent squint. Imaging revealed multiple enhancing lesions located supra- and infratentorially and intramedullary. Histopathological examination demonstrated diffused growth of neoplastic cells. Molecular testing revealed KIAA1549-BRAF fusion and the diagnosis of DLGNT was stated.
