Seizure is a classical feature of intra axial brain parenchymal lesion. Simple bone cyst is an unusual bony pathology at skull base presenting with unexpected symptoms of complex partial seizures. Skull base neuro-endoscopy has managed such lesions more effectively with reduced post-operative morbidity as compared to transcranial approach. This case report discusses a 20-year-old male who presented with 3 episodes of seizure over a time period of 10 months. MRI brain revealed T1 hypo and T2 hyper intense cystic lesion in middle cranial fossa with no enhancement on contrast administration. CT scan showed cystic lesion involving greater wing and pterygoid plate of sphenoid on left side. CT cisternographic evaluation showed CSF outpouching in the sphenoid air sinus. Excision of the cystic lesion was carried out through endoscopic transmaxillary transpterygoid approach. Histopathological examination showed the lesion to be a simple bone cyst.
