Does filum terminale contain CSF?
Lumbar cistern The space inside the arachnoid mater is filled with cerebrospinal fluid (CSF). Below the conus medullaris, this space is enlarged. This enlargement is called the lumbar cistern and contains CSF, the filum terminale, and the cauda equina.
Where is the filum terminale found?
an extension of the pia mater that extends from the terminal end of the spinal cord to the tailbone. The filum terminale helps to anchor the spinal cord in place.
What is a filum terminale cyst?
A filar cyst is an incidental finding on neonatal lumbar sonography located in the filum terminale of the spinal cord. It is considered a normal variant and is often confused for a ventriculus terminalis, a smooth dilated cavity of the central canal, located within the conus medullaris.
What is the cauda equina composed of?
The cauda equina (from Latin horse’s tail) is a bundle of spinal nerves and spinal nerve rootlets, consisting of the second through fifth lumbar nerve pairs, the first through fifth sacral nerve pairs, and the coccygeal nerve, all of which arise from the lumbar enlargement and the conus medullaris of the spinal cord.
Is filum terminale the same as cauda equina?
The fibrous extension of the cord, the filum terminale, is a nonneural element that extends down to the coccyx. The cauda equina (CE) is a bundle of intradural nerve roots at the end of the spinal cord, in the subarachnoid space distal to the conus medullaris.
Is the filum terminale part of the cauda equina?
The cauda equina is composed of the lumbosacral and coccygeal nerve roots and the filum terminale.
Are filum terminale nerves?
In addition, it is surrounded by the nerves forming the cauda equina, from which it can be easily recognized by its bluish-white color. The lower part, or filum terminale externum, closely adheres to the dura mater….

What is the difference between the cauda equina and the filum terminale?
What is the 5th ventricle?
Ventriculus terminalis (VT), also known as the “fifth ventricle”, is an ependymal lined CSF-filled cavity within the conus medullaris. It is formed during embryogenesis via canalization and retrogressive differentiation of caudal spinal cord and regresses completely during early childhood.
What is the filum terminale?
The filum terminale is a structure usually less than 2 mm in diameter. If it is insufficiently elastic (e.g., abnormally thick or fat laden), this can limit the ability of the spinal cord to move cephalad with growth or movement, placing stress on the distal aspect of the conus medullaris (Figs.
What is the filum disease?
As the findings of Dr. M.B. Royo-Salvador’s research of the last 50 years confirmed, a Filum terminale that exerts an excessive traction on the spinal cord causes the Filum Disease. It can consequently be the cause of a clearly defined group of diseases, as well as being closely related to the development of other diagnoses and their prognosis.
What is fatty filum terminale lipoma?
Fatty filum terminale, also known as lipoma of the filum terminale or filar lipoma, is a relatively common finding on imaging of the lumbar spine, and in most cases is an incidental finding of no clinical concern. However, in some patients it may be associated with signs and symptoms of tethered cord syndrome.
What is the history of spinal paraganglioma of the filum terminale?
These tumors may also arise in several other sites throughout the body. Lerman et al (, 76) first described the spinal paraganglioma of the filum terminale in 1972.
