title: The cerebellar and thalamic degeneration in Fukuyama-type congenital muscular dystrophy.
abstract: We report a male autopsy case of Fukuyama-type congenital muscular dystrophy (FCMD), with unusual neuropathological findings. The patient was a Japanese man aged 26 years at the time of death. He had shown severe psychomotor retardation and muscular dystrophy since early infancy, and was diagnosed as having FCMD at the age of 5 years. He died of respiratory failure. The main neuropathological finding was extensive cerebral and cerebellar cortical dysplasia, characteristic of this disorder. In addition, degeneration of the cerebellar efferent pathway, including the dentate nucleus, superior cerebellar peduncle, and red nucleus, and that of the lateral thalamic nucleus were observed. These findings suggest the possibility that the long survival can clarify the latent neurodegeneration in the cerebellum and thalamus in FCMD, in addition to congenital malformations. The system degeneration should be carefully evaluated in the pathological examination of this disorder.
