this cavity is filled with CSF and expands to cause compressive symptoms.
affects spinothalamic pathway bilaterally
spares tracts on lateral borders of spinal cord
presentation of syringomyelia?
Cape-like (bilateral) distribution of pain and
temperature sensation loss
so may be burning themselves often
dorsal columns preserved; fine touch, vibration etc
• DISTAL weakness in UMN pattern - if motor neurones affected too.
where do median,radial and ulnar supply sensation?
google images!

ACA - anterior cerebral artery
which mononeuropathies present as:
Ulnar – claw hand • Median – wasting of LOAF • Radial- wrist drop • CPN – foot drop • VII – UMN forehead spared • VII- LMN forehead involved
Ulnar – claw hand
• Median – wasting of LOAF muscles
• Radial- wrist drop
• CPN – foot drop
- VII – UMN forehead spared

what is a functional episode?
Functional neurological symptoms are neurological symptoms that are genuine, but not due to a disease of the nervous system.
psychiatrists called it “conversion disorder” because patients were thought to be “converting” stress into physical symptoms.
However not all patients experience significant psychological problems. A lot of patients just have an accident or a period of illness and then get functional symptoms afterwards.
Symptoms can include: Loss of motor control Sensory symptoms Speech problems Attacks or seizures Visual symptoms Cognitive problems
