Multiple Sclerosis and Peripheral Multifocal Demyelinating Neuropathies Occurring in a Same Patient

ABSTRACT

The co-occurrence of multiple sclerosis and peripheral demyelinating neuropathy is rare. It has been disputed whether these are pathologically related or coincidental findings. We report a 36-year-old woman who presented with diplopia, right facial palsy and left-sided weakness. Brain magnetic resonance imaging showed a lesion indicative of central demyelinating disease. Nerve conduction studies revealed peripheral multifocal demyelinating neuropathies. We suggest that the central and the peripheral lesions may be continua of a demyelinating process.
