Relationship of the lumbar lordosis angle to the level of termination of the Conus Medullaris and
thecal sac.
Thecal plates were smooth with many scattered pores (Fig.
[4] On flexion-extension MRI, there is forward migration of the posterior
thecal wall compressing the cord causing its flattening and signal changes.
Dhammi and others (4) reported the case of a 2-year-old girl with a calcified disc herniation at T11/12 level accompanied by the
thecal sac herniation.
Within the spinal canal, the dura-mater is the thick outer membrane of the
thecal sac.
Second, the mass effect produced in the epidural space on the adjacent
thecal sac is felt to result in an overall increase in CSF pressure, which translates intracranially and may explain the immediate relief most patients experience following the procedure.
Powell and Martin will both be presented with theAspireAward and Jim Leyland will be honored with
theCal Sr.
The synovial cyst-induced mass effect in the L4-5 intervertebral space,
thecal sac, and right L5 nerve root compression was also detected.
MMP-2 and MMP-9 activities increase during the later period of follicular development and these increments are along with follicular remodeling of granulosa and
thecal cells (8).
[5] Basically, the ovarian follicle consists of two components: An outer
thecal layer and an inner granulose cell layer.
