Multifocal motor sensory demyelinating neuropathy: inflammatory demyelinating polyradiculoneuropathy.
The authors present two cases that provide the first autopsy findings in multifocal acquired demyelinating sensory and motor neuropathy (MADSAMN). Both cases documented multifocal but asymmetric demyelinating neuropathy with rare axonal degeneration. One case clearly documented an inflammatory polyradiculoplexoneuropathy, confirming the inflammatory nature of this neuropathy. This study showed that MADSAMN is an inflammatory demyelinating polyradiculoneuropathy that shares histologic features observed in chronic inflammatory demyelinating polyradiculoneuropathy and multifocal motor neuropathy (MMN), suggesting a similar immunopathogenesis for these entities.
