A 58-year-old woman began to show ataxia at age 45 and dysarthria at age 56. Neurological examination revealed slurred speech, truncal ataxia, and pyramydal sign. Neither history of alcoholism nor hereditary factors were found. The level of serum ammonia was increased. Brain MRI study showed a high signal intensity in the cerebral peduncle and globus pallidus and mild cerebellar atrophy on T1-weighted image. A portal-systemic shunt due to a shunt vessel was found between the left splenic and kidney veins although she did not show any other symptoms or signs due to liver cirrhosis. Her symptoms dramatically improved by an intravenous administration of branched amino acid. The present case suggests an importance in finding a treatable cerebellar ataxia.

Despite popular use of piperacillin, the dire neurotoxicity associated with piperacillin still goes unrecognized, leading to a delay in appropriate management. We report a 57-year-old woman with end-stage renal disease receiving continuous ambulatory peritoneal dialysis (CAPD), who developed slurred speech, tremor, bizarre behavior, progressive mental confusion, and 2 episodes of generalized tonic-clonic seizure (GTCS) after 5 doses of piperacillin/tazobactam (2 g/250 mg) were given for bronchiectasis with secondary infection. The laboratory data revealed normal plasma electrolyte and ammonia levels but leukocytosis. Neurologic examinations showed dysarthria and bilateral Babinski sign. Computed tomography of brain and electroencephalogram were unremarkable. Despite the use of antiepileptic agents, another GTCS episode recurred after the sixth dose of piperacillin/tazobactam. Brain magnetic resonance imaging did not demonstrate acute infarction and organic brain lesions. Initiation of high-flux hemodialysis rapidly reversed the neurologic symptoms within 4 hours. Piperacillin-induced encephalopathy should be considered in any uremic patients with unexplained neurological manifestations. CAPD is inefficient in removing piperacillin, whereas hemodialysis can rapidly terminate the piperacillin-induced encephalopathy.
