The endoscope has been increasingly used to treat various spinal diseases. However, the application of spinal endoscopy in an intradural lesion has been less common compared to that of an epidural counterpart. The authors reviewed existing literature describing spinal endoscopy as an aid in surgical treatment for intradural pathologies. Importantly, available literature indicated the safety and feasibility of spinal endoscopy for intradural lesions. Especially, an endoscope was utilized for intradural subarachnoid cystic lesions, tethered cord syndrome, extramedullary tumors, spinal arteriovenous malformations, and cordectomy for intractable pain. The results of this review should enhance further development and broaden application of an endoscope for various intradural pathologies.
