What Is The Prognosis For The Condition Myelomalacia?

Is the term Myelomalacia somewhat ambiguous? I ve read it can mean the following: - a specific progressive condition of bleeding in the spinal cord leading to paralysis and death - a generic term for any observed increased signal intensity on MRI of the cord - a generic term meaning damage to the spinal cord - a generic term meaning softening of the spinal cord - a generic term meaning bruising of the spinal cord
