Pathology of Syringomyelia Due to Chiari Malformations

摘要: Since the early nineteenth century, some authors have used term syringomyelia to describe any tubular cavity within spinal cord. More recently, classification systems evolved subtypes as well distinguish other entities such hydromyelia, syringobulbia, and myelomalacia. Our current understanding of etiology syringomyelia, although more advanced, is still incomplete. Syringomyelia occurs in many different clinical settings with variable symptomatology cavitary patterns. Anatomic pathologic criteria are helpful establishing basic syringes ­understanding setting Chiari malformation. The pathophysiological hypotheses for numerous, controversial, according proximate cause. gross pathology histology similar irrespective cause, competing theories continue evolve on pathogenesis syrinx formation.
