Acute motor sensory polyneuropathy (AMSAN) complicating active ulcerative colitis with a patchy distribution.
We report a case of acute motor and sensory neuropathy during a flare of ulcerative colitis. A 28-year-old male presented with a flare of distal ulcerative colitis despite treatment with mesalamine enemas and suppositories simultaneously with rapidly deteriorating weakness and needle sensation in both legs. Neurological assessment showed axonal sensorimotor polyneuropathy affecting mainly the lower limbs and to a lesser extent the upper limbs. Colonoscopy revealed moderately to severe active ulcerative colitis with a patchy distribution involving the rectum and the right colon. Vitamin and folic acid levels were normal. Virological, immunological and other laboratory tests were negative except for positive anti-ganglioside antibodies (anti-GM1). Ulcerative colitis and polyneuropathy improved when patient was treated with immunosuppressive therapy (corticosteroids, immunoglobulin and azathioprine). Peripheral polyneuropathy is a rare extraintestinal manifestation of ulcerative colitis and it is probably associated with an autoimmune pathogenetic mechanism.
