Anti-GD1b Disorder Presenting as Multiple Mononeuropathies.

Isolated anti GD1b disorders are quite rare. They usually present with ophthalmoplegia, sensory ataxia, paraproteinemia, and elevated cold agglutinants. The response to immunosuppressant treatment does not seem to be very effective. We report a case of isolated mononeuropathies associated with isolated anti-GD1b antibodies, without ataxia or paraproteinemia with dramatic response to short course of steroid treatment.
