title: Papillary glioneuronal tumour of the precentral gyrus.
abstract: The article describes a case of a 15-year old boy after a head contusion with a five-month history of headaches and two seizure episodes. MR imaging revealed a partly solid and partly cystic cortical-subcortical tumour within the precentral gyrus with post-contrast enhancement. The patient underwent gross total resection of the lesion. Histologically the neoplasm was composed of pseudopapillary gliovascular structures surrounded by solid glioneuronal tumour areas. The expression of GFAP and nestin characterized the central parts of the tumour. Moreover the immunolabelling for synaptophysin, neurofilaments, Olig2 and NCAM was present in the peripheral part of the lesion. The neoplasm was consistent with a papillary glioneuronal tumour - one of the new entities in the last WHO CNS tumour classification.
