We report the case of a 22 year old woman with congenital generalized lipodystrophy who presented a left brachiocrural pyramidal hemisyndrome, bilateral cerebellar signs and a left cranial nerve VI deficit. The clinical pattern had a tendency to regress. MRI brainscan, CSF examination and clinical features led to the diagnosis of "probable demyelinating syndrome". Published data on CNS involvement in patients with congenital generalized lipodystrophy are few and we have found no cases in which a demyelinating syndrome is associated. In the case we report it is tempting to see the disorder of the lipid metabolism underlying the congenital generalized lipodystrophy as underlying the myelin disorder as well.
