End-filament lipoma is an abnormal infiltration of end-filament fibers and is a type of spinal lipoma.
Terminal filaments are thin filaments of the spinal cord, and the spinal cord forms a membranous structure without neural tissue during growth and development. It connects the end of the cones of the spinal cord to the dorsal aspect of the vertebrae of the caudal vertebrae, and extends posteriorly within the dural sac, and merges with the dural filaments of the spinal cord at the posterior end of the sac.
Fatty degeneration of the terminal filaments is most commonly seen in spinal embolism syndrome, which is a manifestation of degenerative changes of the terminal filaments. Moreover, it is surrounded by lumbar, sacral, and caudal spinal nerves, which can easily compress the local nerves, resulting in pain in the nerve area and symptoms such as numbness.
If there are symptoms, it is recommended to go to the hospital as soon as possible, and if necessary, cooperate with the doctor as soon as possible to use surgical methods of treatment.
