No abnormalities were seen on magnetic resonance imaging (MRI) performed in the dog in dorsal recumbency and the hips in a neutral … Medullary cone movement in subjects with a normal spinal cord and in patients with a tethered spinal cord. Physical examination findings and plain radiographs were reviewed in an attempt to correlate these findings with subsequent intraspinal pathology. The spinal cord performs a variety of essential functions, sending messages to and from the brain that travel around the body. The tethered cord syndrome (TCS), also known as tight filum terminale syndrome is a clinical entity by which signs and symptoms are caused by excessive tension on the spinal cord.The majority of cases of tethered cord are related to spinal dysraphism.

Radiology. There were 23 adult patients versus 50 children with tethered cord treated in Sofuoglu et al. That MRI came back showing the conus to be abnormally low (lowest part of L3) and suspicious for tethered cord (no fatty filum). 1 TCS is caused by abnormal spinal cord fixation when secondary neurulation is disturbed. MRI: A diagnostic test that, using powerful magnets and computer technology, produces three-dimensional images of body structures; can show the spinal cord, nerve roots, and surrounding areas, as well as enlargement, degeneration, and displacement 12. Magnetic resonance imaging of the spine (Figure 3) showed complete separation of the spinal canal, thecal sac, and neural tissue at about the L2 level by a midline bony spur, a coexisting tethered spinal cord, and a dermal sinus tract. At That MRI came back showing the conus to be abnormally low (lowest part of L3) and suspicious for tethered cord (no fatty filum). Detection, staging, and post-treatment evaluation of tumor of the knee; or Persistent knee pain/swelling and/or instability (giving way) not associated with an injury and not responding to at least 3 weeks of conservative … The cord is tethered in the low sacral region, with a small lipomatous mass also identified in the region of tethering. The most common findings in adults are low-lying conus (below L2 vertebra) with intra- or extradural lipoma and a short, thickened filum terminale greater than 2 mm in diameter. 3. Radiology. 2001. Disc herniation refers to the displacement of intervertebral disc material beyond the normal confines of the disc but involving less than 25% of the circumference (to distinguish it from a disc bulge).A herniation may contain nucleus pulposus, vertebral endplate cartilage, apophyseal bone/osteophyte and annulus fibrosus.. Disc herniations can be divided into groups in a variety … It provides a detailed delineation of pathologic spine conditions, especially those involving the thecal sac and its contents. Tethered spinal cord. MRI is the imaging modality of choice for evaluating a tethered cord in older children, and can show the location of the conus medullaris (normally superior to L3), assess the thickness of the filum terminale (normally less than 2 mm in cross-sectional diameter), identify traction lesions, and show associated bony dysraphisms (Photo 4) A lump of the lower back. [ 1 ] A tethered spinal cord or TCS, is a congenital neural tube malformation described as a spinal cord that extends lower than the L1/2 intervertebral disc space. T1-weighted MRI demonstrated a conus ending at L3 with T1 hyperintensity of the filum terminale, indicative of fatty infiltration. Various forms include tight filum terminale, lipomeningomyelocele, split cord malformations (diastematomyelia), dermal sinus tracts, and dermoids.All forms involve the pulling of the spinal cord at the base of the spinal canal, literally a … Background and Aim: Tethered spinal cord is the most common anatomic deformity which is usually diagnosed in childhood.This study aimed to describe the different anatomo-radiological patterns of the tethered spinal cord with lipoma. 26 Its prevalence among children and adults undergoing MRI for unrelated reasons is 1.5% to 4%.
