We have other two cases, both in the temporal stem, one after pituitary apoplexy (most likely in macroadenoma but no surgical confirmation), and the other one after surgical resection of a cranial vault meningioma invading the superior sagittal sinus (far away from the dilated temporal stem PVS). We are trying to publish these last two cases.</p> <p>Has anyone other cases? Which is the frequency of regression of dilated PVS? Is it frequent, and we simply do not look for this?<br /> Best regards to all of you.</p> ]]></content:encoded> </item> <item> <title>Spinal Cord Herniation</title> <link>https://www.ajnrblog.org/2009/03/06/spinal-cord-herniation/</link> <comments>https://www.ajnrblog.org/2009/03/06/spinal-cord-herniation/#comments</comments> <dc:creator><![CDATA[Alfonso CERASE]]></dc:creator> <pubDate>Fri, 06 Mar 2009 21:03:31 +0000</pubDate> <category><![CDATA[Spine]]></category> <category><![CDATA[Brown-Sequard syndrome]]></category> <category><![CDATA[Spinal cord thoracic herniation]]></category> <guid isPermaLink="false">http://www.ajnrblog.org/?p=644</guid> <description><![CDATA[This is a case for Prof. Dr. Dillon.

There was no history of trauma or surgery; neurological examination revealed features suggestive of thoracic level Brown-Séquard syndrome.</p> <p style="text-align: center;"><a href="http://www.ajnrblog.org/wp-content/uploads/fig_cerase.jpg"><img loading="lazy" decoding="async" class="size-medium wp-image-653 aligncenter" title="fig_cerase" src="http://www.ajnrblog.org/wp-content/uploads/fig_cerase-300x190.jpg" border="0" alt="fig_cerase" width="300" height="190" /></a></p> <p style="text-align: left;">The patient underwent a thoracic laminectomy at T9–T10. The dura was opened under the microscope and an atrophic spinal cord displaced to the left was visible. The spinal cord was incarcerated through a 2.5 cm wide anterolateral dural defect and had an exophytic edematous appearance. In order to perform an anterior untethering, the dentate ligament was transected and the nerve roots were preserved. The spinal cord was gently mobilised out of the dural defect. Notably, there were no major adhaesions and thus there was no need to manipulate the cord. Then, it was decided to position hemostatic material (Spongostan®) and glue (Tissucol®) around the defect and finally a sheet of collagenous membrane (DuraGen®) anterior to the spinal cord. The wound was closed in layers without external cerebrospinal fluid drainage. No spinal cord monitoring was used. The initial post-operative neurological deficit was unchanged and there was no sign of cerebrospinal fluid leakage. The patient was discharged seven days after surgery to rehabilitation.</p> <p>Best regards to all of you.</p> <p style="text-align: center;"><a href="http://www.ajnrblog.org/wp-content/uploads/figure-2.jpg"><img loading="lazy" decoding="async" class="size-medium wp-image-676 aligncenter" title="figure-2" src="http://www.ajnrblog.org/wp-content/uploads/figure-2-300x218.jpg" alt="figure-2" width="300" height="218" border="0" /></a></p> <p><a href="http://www.ajnrblog.org/wp-content/uploads/isch-cerase-20091.ppt" target="_blank"><strong>ISCH</strong> <strong>Cerase (.ppt)</strong></a></p> ]]></content:encoded> <wfw:commentRss>https://www.ajnrblog.org/2009/03/06/spinal-cord-herniation/feed/</wfw:commentRss> <slash:comments>3</slash:comments> </item> </channel> </rss>
