Case Report of Fibrolipomatous Filum Terminale in Korean Cadaver / 대한해부학회지

ABSTRACT

Tethered cord syndrome is a symptom complex result from tightening of film terminale. Thickened filum terminale, lipomyelomeningocele, diastematomyelia, dermal sinus tract, intradural fibrous adhesion, and spinal lipoma might cause the tightening. The common mechanism of these injury is suggested an impairment of longitudinal movement of the sinal cord, especially conus medullaris, which subsequently leads to chronic local ischemia. During cadaver dissection, we have observed low conus medullaris (L4) and thickened film terminale with intradural lipoma in 51 years old female. Thickened film terminale merged into lipomtous cyst located in lower marin of sacral canal. These morphologic findings is considered a lipomatous film terminale, which might cause tethered syndrome.
