What are the differences between ependymoma and astrocytoma?
a) Ependymoma is a tumor derived from ependymal cells, while astrocytoma originates from astrocytes.
b) Ependymoma primarily occurs in the brain, while astrocytoma can occur in both the brain and spinal cord.
c) Ependymoma is more common in children, whereas astrocytoma can occur in both children and adults.
d) Ependymoma is more likely to cause obstructive hydrocephalus due to its location in the brain's ventricular system, whereas astrocytoma may cause increased intracranial pressure due to mass effect.
