title: Intramedullary dermoid in a low lying conus tethered by a fatty filum - embryological implications.
abstract: Intramedullary dermoids arising within the conus medullaris are rare. We report a rare association of an intramedullary dermoid cyst located in a low lying conus tethered by a thickened, fatty filum terminale and discuss the embryological implications of this association.
