Wei-Che Wang, Hsiu-Chun Yang, Yao-Jen Chen Department of Physical Medicine and Rehabilitation, Chung Shan Medical University Hospital, Taichung, Taiwan Abstract: Acute-onset alcohol-associated neuropathy is only occasionally reported, and delayed postanoxic encephalopathy is rare. Here, we report a male who developed acute multiple focal neuropathies and later delayed postanoxic encephalopathy after alcohol intoxication. He had hypoxia and rhabdomyolysis, presenting with acute renal failure initially, and cardiopulmonary support, including mechanical ventilation, led to improvement of the patient at the acute stage. He suffered from bilateral hand numbness and mild weakness of the right lower limb thereafter. Nerve-conduction study revealed no pickup of compound muscle action potential or sensory nerve action potential in the bilateral ulnar nerve, but showed attenuated amplitude of compound muscle action potential in the right femoral nerve. Multiple focal neuropathies were suspected, and he received outpatient rehabilitation after being discharged. However, the patient developed gradual onset of weakness in four limbs and cognitive impairment 23 days after the hypoxia event. Brain computed tomography showed low attenuation over bilateral globus pallidus, and brain magnetic resonance imaging disclosed diffuse increased signal intensity on T2-weighted images and fluid-attenuated inversion recovery in bilateral white matter. He was admitted again under the impression of delayed postanoxic brain injury. Supportive treatment and active rehabilitation were given. He had gradual improvement in motor and functional status after rehabilitation. He could walk with festinating gait under supervision, and needed only minimal assistance in performing activities of daily living approximately 1 year later.
