Motor neuron disease with pallido-luysio-nigral atrophy.
A case of motor neuron disease (MND) with pallido-luysio-nigral atrophy (PLNA) is reported. The 45-year-old male patient presented with lower motor neuron symptoms and signs of basal ganglia disturbance. He died after a progressive course of 7 months. Neuropathological examination revealed motor neuron loss at all spinal cord levels with sparing of Onuf's nucleus. Nerve cell loss and gliosis were also present in substantia nigra, globus pallidus, and subthalamic nucleus. The presence of ubiquitin-positive inclusions, a hallmark of most variants of MND, confirms this case as an example of MND. At immunoelectron microscopy the granules were distributed on filamentous material. The combination of clinically apparent PLNA with MND has only been described twice previously. The relationship of this syndrome to other forms of MND and its nosological placement are discussed.
