Spinal CSF drop metastasis of an unsual malignant glioneuronal tumour of the brain

Cerebral malignant glioneuronal tumours (MGNT) are rare and therefore hardly described in literature. Histopathologically they are characterized by mixture of glial- and neuronal-type differentiated cells. MGNT show high polymorphism but are generally similar to malignant glioma (WHO classification Grade III and IV), so they may be underdiagnosed. Despite this similarity they demonstrate a special entity of tumours with a typical pathology and differing clinical characteristics. Here, we report an unusual case of a malignant glioneuronal tumour with spinal metastasis. Case report: A 52-year old man presented wit…
