This 20 month old boy underwent T9-L1 laminotomy, decompression of spinal cord,
and biopsy of epidural yolk sac tumor. He was discharged on October 27 following a
course of chemotherapy. He died 2 days later unexpectedly.
The autopsy revealed a paravertebral tumor with extension to the vertebral bodies.
No epidural tumor was present. The tumor was largely composed of yolk sac tumor
with a minor component of teratomatous elements.
The cause of unexpected death is not completely clear. However, hypernatremia was
an important factor contributing to death.
