Abstract
The clinical and pathological findings of a 41-year-old male patient with atypical Charcot-Marie-Tooth disease were reported. There were 3 cases of subarachnoid haemorrhage, 2 nerve deafness and 2 hereditary motor and sensory neuropathy (HMSN) in his family.
He had suffered from progressive nerve deafness since 5 years old and gait disturbance since 37 years old. He had been admitted to the psychiatric hospital 3 times because of hallucinatory-delusional state and behavior abnormalities.
Neurological examinations at 39 years old revealed that he had mental deterioration (IQ 66), nerve deafness, diffuse muscle atrophy, most marked distally, sensory disturbance, areflexia, positive Romberg's sign, orthostatic hypotension, dysphagia and slurred speech. MCV of median nerve was 27.8 m/sec, and SCV was not evoked. EEG revealed nonspecific dysfunction of the brain.
He died of ileus-like condition at 41 years old. General autopsy showed haemorrhagic infarction of the jejunum and ileum due to compression of the superior mesenteric artery and vein by an adhesion band of connective tissue formed after previous appendectomy.
Neuropathological examinations revealed axonal degeneration and loss of myelinated fibers with schwannosis of anterior and posterior spinal nerve roots as well as peripheral nerves. The posterior roots were more severely affected than the anterior ones. Ganglion cells of the posterior root ganglia showed remarkable degeneration and loss. There was severe degeneration of the posterior columns, especially in the gracilis, of the spinal cord. Nerve cells in the anterior horns and Clarke's columns also displayed conspicuous atrophy or central chromatolysis followed by gliosis. There was slight degeneration of the posterior spinocerebellar tracts.(ABSTRACT TRUNCATED AT 250 WORDS)
