CT myelography of subarachnoid leukemic infiltration of the lumbar thecal sac and lumbar nerve roots.
Spinal nerve root or cauda equina compression in patients with leukemia is often secondary to extradural chloroma [1]. We present the CT myelographic findings of an intradural mass and lumbar nerve root enlargement secondary to leukemic infiltration of the lumbar subarachnoid space and nerve roots. This form of leukemic involvement of the nervous system has not previously been demonstrated with...
متن کاملCT myelography of a fragment of a lumbar disk sequestered posterior to the thecal sac.
The radiologic manifestations of lumbar disk herniation as seen on myelography, postmyelography CT, and, more recently , surface-coil MR have been well described (1-3). CT and MR findings of far lateral , extraforaminal disk herniation also have been reported (4]. Migratory fragments typically settle anterior and/or lateral to the thecal sac (5]. We report a case in which the sequestered migrat...
متن کاملRelationship of the Lumbar Lordosis Angle to the Level of Termination of the Conus Medullaris and Thecal Sac
The level of termination of the conus medullaris (CM) and thecal sac (TS) is subject to variations. We try to correlate in this study these variations with the lumbar lordosis angle (LLA) using MRI scans. A retrospective study was conducted using available MRI scans of the lumbar spine. The CM level of termination (CMLT) and the TS level of termination (TSLT) were identified according to a vert...
متن کاملCaudal Regression Syndrome in a 12-Year-Old Boy Associated with Thecal Sac Ending at Fifth Lumbar Vertebrae Associated with Caudal Stenotic Dural Sac and Thickened Filum Terminale, Bifid Lumbar Vertebrae with Sacral Vertebral Agenesis: Pentads Defects
Caudal regression syndrome is a rare congenital anomaly with characteristic agenesis or dysgenesis of caudal vertebrae varying from isolated partial agenesis of coccyx or entire lumbosacral vertebrae.1,2 It may be associated with congenital anomaly of spinal cord, genitourinary tract, and gastrointestinal tract.3–5 The children with extensive bony defects in caudal regression syndrome may prese...
متن کاملReliability of assisted indentation in measuring lumbar spinal stiffness.
The reliability of manual methods to assess spinal stiffness is modest at best. In response, instrumentation has been developed which may be reliable, but is often difficult to use in clinical settings. The purpose of this study was to determine the intra-rater reliability of assisted indentation (AI), a smaller, less automated technique of measuring spinal stiffness in vivo. Twenty-three asymp...
