[Abstract] Objective: To summarize the clinical, pathologic and imaging characteristics of multinodular and vacuolating neuronal tumors (MVNT) and improve the knowledge about this disease.Materials and Methods: Relevant English literature was reviewed and features of the reported MVNT cases were summarized. Accordingly, the cases with typical imaging findings of MVNT in local database were searched and their clinical and imaging featuers were analyzed.Results: Until January 2018, there are 87 MVNT with sufficient data had been reported in English literature. Among them, 31 cases were histologically proved. The mean age at presentation was 41(6—71) years old. A female predominance was observed. The clinical presentation included seizures/suspected seizure (1 episode), headache and nonspecific symptoms. Histologically, the MVNT consisted of multinodular tissue, with varying degrees of matrix vacuolization which indicated a dysplastic early neuronal phenotype. The tumors were located principally within the deep cortical ribbon and superficial subcortical white matter. Imaging findings corresponded well with the histologic features. Typical imaging features consisted of a cluster of variably sized nodular lesions located in the subcortical ribbon and superficial subcortical white matter following the gyral contour. They appeared hyperintense on T2WI and FLAIR images, and typically do not enhance or cause mass effect. There are 12 cases of MVNT with typical features identified among about 100 thousand cases in our database.Conclusions: MVNT is a benign lesion with typical histologic and imaging features. With improving knowledge of the features, most of the MVNTs may be diagnosed with neuroimaging without the need of biopsy.
