What is the Yolk Sac Tumour (Spinal Cord)?The yolk sac tumour (spinal cord) is a rare type of tumour that arises due to the failure of germ cells (eggs and sperms) to reach ovaries and testicles during the embryonic stage of life and start growing abnormally in the spinal cord and form a tumour. It is commonly developed in children between the ages of 1, and 2 years but can develop in people of all ages.
Disease CausesThere is no well-known cause; however developmental birth defects of the brain and spinal cord, genital systems, and urinary systems can contribute to the development of yolk sac tumour (spinal cord).
Signs and SymptomsThe patient may suffer from the following signs and symptoms. These are
- Pain in the back
- Difficulty in walking or writing

- Imaging techniques like Chest X-ray, CT-scan, MRI, and PET scan to see the site, size, and extent of the tumour.
- Tumour biopsy (tumour biopsy to remove a small sample of tissue for histopathological examination)
- USG-guided fine needle aspiration cytology
