Definition : 1. A fully and normally developed disc with no changes attributable to trauma, disease,
degeneration, or aging. The bilocular appearance of the adult nucleus is considered
a sign of normal maturation. 2. (Non-Standard) [A disc that may contain one or more
morphologic variants which would be considered normal given the clinical circumstances
of the patient.]. Note: Many congenital and developmental variations may be normal
in that they are not associated with symptoms; certain adaptive changes in the disc
may be normal considering adjacent pathology, and certain degenerative phenomena may
be normal given the patient's age; however, classification and reporting for medical
purposes is best served if such discs are not considered normal. What is clinically
normal for a given patient is a clinical judgment independent of the need to describe
any variation in the disc itself. AJNR;
