“…Second, the reported incident rate of readhesion is low, and third, the decompression effect is maintained for a long period because the inner layer of the dura mater is preserved. 15 In addition, because this foramen magnum decompression procedure is extradural, there are no demonstrated risks of such postoperative complications 6 as cerebrospinal fluid collection in the operative wound, 4 pseudomeningocele 10 or meningitis. 9,16 Therefore, the authors are convinced that this method is advantageous when performing a foramen decompression in an elderly patient.…”

Study design: Report of a rare case of an elderly patient with late onset of Arnold Chiari malformation type I with associated syringomyelia that was successfully treated with foramen magnum decompression. Objective: To report this rare case along with a literature review. Setting: Gifu, Japan. Methods: A 69-year-old woman with a 4-year history of dull pain in her right arm was referred to the clinic. After physical and radiographical examinations, she was diagnosed with Arnold Chiari malformation type I with associated syringomyelia. A foramen magnum decompression by the removal of the outer layer of the dura mater was performed. Results: At 2 years postoperatively, MRI revealed a decrease in the size of the syringomyelia. Her symptoms had also remarkably improved. Conclusions: A rare case of symptomatic Arnold Chiari malformation type I with associated syringomyelia in an elderly woman was successfully treated with foramen magnum decompression by the removal of the outer layer of the dura mater.Spinal Cord (2005) 43, 249-251.
