Abstract
DNET is a low grade cortical neoplasm which closely resembles cortical dysplasia on magnetic resonance imaging (MRI). It is usually non-enhancing but can show some enhancement on about one third of case. Rarely enhancement can be ring like and when the mass is large in size, it can cause considerable diagnostic problem from higher grade gliomas. However, age of the patient and associated features like calcification, lack of mass effect and long duration of symptoms should assist in reaching the correct diagnosis. Dysembryoplastic neuroepithelial tumour (DNET) is low grade cortical glioma which is most commonly seen in temporal lobe. It is usually a non-enhancing tumour but sometimes it can show enhancement and occasionally it can be ring like, which can cause diagnostic confusion with higher grade gliomas. We report a case of DNET which showed ring like enhancement of post contrast images.
