FD American Society of Neuroradiology SP 1312 OP 1315 VO 16 IS 6 A1 R T Andrews A1 T M Koci YR 1995 UL http://www.ajnr.org/content/16/6/1312.abstract AB A patient who underwent lumbar spine surgery sustained an occult dural injury. After unrecognized suction drainage of cerebrospinal fluid through a surgical drain, caudal herniation of the cerebellum with superior cerebellar infarction developed. This mechanism should be considered in patients in whom acute mental status changes develop after spinal surgery.
