They are almost identical to the proximal thecal
hoods of the older species G.
Decreased proliferation of thecal
capillary endothelial cells leads to reduced thecal
vasculature, which is one of the earliest events during follicular atresia.
Magnetic resonance (MR) imaging demonstrated extensive posterior spinal epidural mass from T9 through L4 causing compression of the spinal cord and thecal
A number of radiographic features identifying dural ectasia have been suggested including a dilatation of the dural sac with the diameter of the thecal
sac at S1 level greater than the diameter at L4 level,[sup.
Recent POFs are amorphous and clearly show multiple infoldings of thecal
and granulose cells Oocytes in the largest batch are 300-550 pm in diameter.
As in this case, most patients present with progressive low back and lower extremity radicular symptoms resulting from compression of the thecal
sac or nerve roots.
A laminectomy at L5 and S1 levels was performed, and the thecal
sac was ligated and mobilized superiorly.
MRI of the thoracolumbar spine demonstrated a dorsally located intraspinal extradural cystic lesion extending from T3 to T10 with indentation to the thecal
sac but without severe compression.
The most commonly extended explanation for EVE is thecal
compression due to the volume effect on consequent epidural injection of fluid (4).
Gilling-Smith C, Willis DS, Beard RW, Franks S Hypersecretion of androstenedione by isolated thecal
cells from polycystic ovaries.
Infiltration of the epidural space takes place through the intervertebral foraminae, leading to compression of the thecal
7) The high contrast between adipose tissue and the thecal
sac on T1-weighted MRI permits an accurate evaluation of the extent of pathologic epidural tissue overgrowth in the spinal canal.
