Abstract

Dysembryoplastic neuroepithelial tumours (DNET) are a rare, typically benign glial- neuronal cortical tumour that most commonly manifests in children and young adults as intractable seizures. The key benefit of awake craniotomy in multi-drug resistant intractable seizures caused by DNET in eloquent areas especially in and around motor cortex is to do safe maximal resection, preserving motor functions and seizure free outcome. A 16 year old adolescent presented with refractory sensory seizures for 7 years. MRI Brain was done showing left parietal lesion suggestive of DNET with focal cortical dysplasia (FCD). Awake craniotomy was done with the help of neuronavigation and gross total resection of lesion was achieved. Biopsy reported as DNET with FCD. Post operatively patient was seizure free. DNET associated with FCD in parietal region is very rare. Cortical dysplasia is commonly associated with DNET and appears to contribute to the DNET's epileptogenic activity. For optimal disease treatment, surgical treatment should aim to remove DNET with FCD. We found awake craniotomy with neuronavigation helps to resect the lesion maximally with no or minimal neurological deficits.
