ABSTRACT
Diffuse leptomeningeal glioneuronal tumor (DLGNT) is a rare, low-grade neoplasm, which is newly categorized into the neuronal and mixed neuro-glial tumor in 2016. The most characteristic imaging findings are diffuse leptomeningeal thickening and enhancement with multiple minor cysts. This article described a case with DLGNT mimicking meningitis, whose cystic lesions were not obvious, with swollen multiple lobes cortex, gyri form cortical calcification and enhanced meninges. Meningeal irritation sign repeated attacks and the clinical symptoms gradually improved after steroid pulse therapy. The biopsy and immunohistochemistry staining were diagnosed as DLGNT. The imaging features and clinical data of this case were analyzed to improve the understanding of the disease in clinical practice.
