[Alcoholic cerebellar degeneration with pyramidal sign--in relation to alcoholic myelopathy].

Two cases of alcoholic cerebellar degeneration with pyramidal sign were reported. Patient 1 with alcohol dependence syndrome was a 46-year-old woman. After the alcohol abuse of about eight years, she complained of gait disturbance. The gait disturbance progressively worsened in about two months and she could not ambulate freely by herself. Neurological examination revealed nystagmus, ataxic and spastic gait, slight weakness and spasticity of the lower extremities, hyperreflexia of the extremities, bilateral Babinski's signs, and incoordination of the lower extremities. Examination of liver function and serum B12 was normal. Cranial CT scan and MRI revealed atrophy of the cerebellar vermis and dorsal part of the cerebellum. Though neurological signs slightly improved after the admission to our hospital and the abstinence from alcohol abuse, ataxic gait and hyperreflexia of the extremities have continued. Patient 2 was a 58-year-old man. He was a heavy drinker, but was not a patient with alcohol dependence syndrome. After the heavy drinking of about 40 years, he complained of gait disturbance. The gait disturbance had progressively worsened in about four months. Neurological examination revealed ataxic gait, hyperreflexia of the lower extremities, and bilateral Babinski's signs. Laboratory examination revealed slight liver dysfunction with minimal GPT and moderate gamma-GTP elevation. Examination of serum B12 was normal. Cranial CT scan and MRI revealed atrophy of the cerebellar vermis. Though bilateral Babinski's signs disappeared after the abstinence from heavy drinking, ataxic gait and hyperreflexia of the lower extremities have continued. Alcoholic myelopathy without hepatic cirrhosis was rarely reported. In the relation of alcoholic cerebellar degeneration to alcoholic myelopathy, our cases are interesting and important.
