DYSEMBRYOPLASTIC NEUROEPITHELIAL TUMOR AS A CAUSE OF COMA

Dysembryoplastic neuroepithelial tumour (DNT), a non-evolutive intracr anial cortical lesion, is generally associated with epileptic seizures principally among youths. A case of a DNT which presented with uncomm on clinical features, characterized by severe intracranial hypertensio n and progressive blindness warranting emergency surgery, is documente d. In addition to the classical radiological and neuropathological fea tures characteristic of DNTs there was a large haemorrhagic cystic hae matoma as a result of repeated dissections and/or ruptures of the abno rmal vessels in areas, explaining some of the atypical clinical sympto ms. Therefore the need for a regular, careful clinical and radiologica l follow-up of cases with cystic DNTs is strongly recommended.
