RT Journal Article SR Electronic T1 Degeneration of fasciculus gracilis in cystic fibrosis JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 185 OP 185 DO 10.1212/WNL.27.2.185 VO 27 IS 2 A1 ALAN GELLER A1 FLOYD GILLES A1 HARRY SHWACHMAN YR 1977 UL http://n.neurology.org/content/27/2/185.abstract AB The spinal cords of 19 percent of patients dying with cystic fibrosis after 5 years of age showed posterior column degeneration. The risk did not appear to increase with advancing age. None of these patients had findings of pernicious anemia or spinocerebellar degeneration. The lesions had been undetected clinically. It is possible that nutritional, toxic, or hereditary factors may play a role in producing this lesion.
