Spinal pilocytic astrocytoma: MR imaging findings at first presentation and following surgery.
OBJECTIVE
The objective of this article is to describe MR imaging findings of spinal cord pilocytic astrocytomas at first presentation and following neurosurgery and to discuss briefly some of the most common differential diagnoses.


CONCLUSIONS
MR imaging findings in medullary pilocytic astrocytomas consist generally of focal or diffuse cord-enlarging masses that are irregularly shaped, accompanied by cystic elements and hydromyelia, present different degrees of contrast enhancement, high water diffusivity and a propensity for the thoracic and cervical cord.
