Fibrolipomas of the filum terminale are usually more caudally located and generally much smaller.
In 1953 Garceau hypothesized that spinal cord traction was caused by a tight filum terminale.[4] He discovered that after cutting the filum terminale, patients would recover from incontinence and neurological deficits in their legs.
Abnormal fusion of these germ layers can result in nonfusion of the embryonic halves of the vertebral arches or spina bifida.[11] Mesodermal and epidermal tissue fill the space left vacant by incomplete neurulation and result in such abnormalities as a dermal sinus tract, lipomyelomeningocele, diastematomyelia, and tight filum terminale, all associated with spina bifida occulta.[15]

Closed spinal dysraphisms such as diastomatomyelia, dermal sinus, terminal myelocystocoele, lipomas, thickened filum terminale, tethered cord and sacral spina bifida have been described in the literature.
These tumors typically arise from the ependymal glia of the conus medullaris and filum terminale. On the basis of their location, they present with lower back, leg, or sacral pain, and muscle weakness or sphincter dysfunction.
