[Intraspinal calcifications. Symptomatology. Pathologic value]

Calcifications in the spinal canal on plain films are not an unusual finding. The authors present 22 such cases. Identification and pathological value depend on the topography and morphology of these calcifications. The calcifications have been classified in three groups: anterior, median and posterior. The most common etiologies for the anterior ones were calcifications of the posterior longitudinal ligament and calcified discal hernias; meningiomas were the most common cause of the median calcifications; ligamentum flavum calcifications accounted for must of the posterior ones.
