Final answer:
Syringomyelia can be caused by trauma, tumors, or Chiari I malformation. All these factors can disrupt the normal flow of CSF or direct damage to the spinal cord, leading to the formation of a syrinx.
Step-by-step explanation:
Syringomyelia is a condition that involves the formation of a fluid-filled cyst, or syrinx, within the spinal cord. This can lead to a variety of symptoms, including pain, weakness, and sensory impairment.
The possible causes of syringomyelia include: 1) Trauma, such as injuries resulting from accidents that may lead to spinal cord damage; 2) Tumors within the spinal cord that can obstruct fluid flow and create cysts; and 3) Chiari I malformation, which is a condition where brain tissue extends into the spinal canal, potentially disrupting the flow of cerebrospinal fluid (CSF) and causing syringomyelia.
The correct answer among the provided options is 4) All of the above, as all these factors can contribute to the development of the condition.
