 1.                Basis for determining the factors
On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that arachnoid cyst and death from arachnoid cyst can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.
 1.                Factors that must exist
At least one of the following factors must exist before it can be said that, on the balance of probabilities, arachnoid cyst or death from arachnoid cyst is connected with the circumstances of a person's relevant service:
 1.           having a moderate to severe traumatic brain injury before clinical onset of cranial arachnoid cyst;
 2.           having concussion or a moderate to severe traumatic brain injury within the 3 months before clinical worsening of cranial arachnoid cyst;
 3.           having trauma in the region of the affected site before clinical onset of spinal arachnoid cyst;
Note: trauma is defined in the Schedule 1 - Dictionary.
 1.           having trauma in the region of the affected site, within the 3 months before clinical worsening of spinal arachnoid cyst;
Note: trauma is defined in the Schedule 1 - Dictionary.
 1.           undergoing spinal surgery in the region of the affected site before clinical onset of spinal arachnoid cyst;
 Note: Examples of spinal surgery include spinal fusion, laminectomy, discectomy and interspinous device insertion.

 1.           having intrathecal catheter placement, including lumboperitoneal shunt and spinal anaesthesia, or inadvertent dural puncture during epidural injections or epidural anaesthesia, in the region of the affected site, before clinical onset or clinical worsening of spinal arachnoid cyst:
 2.           having a myelogram before clinical onset or clinical worsening of spinal arachnoid cyst;
 3.           having one of the following infections before clinical onset or clinical worsening:
         1.           bacterial infection of the brain or spinal cord, including abscess;

 4.       having a subarachnoid haemorrhage within the cranium or spinal canal before clinical onset or clinical worsening of arachnoid cyst;
 5.       having spinal adhesive arachnoiditis before clinical onset or clinical worsening of spinal arachnoid cyst;
 6.       inability to obtain appropriate clinical management for arachnoid cyst before clinical worsening.
 1.            Relationship to service
