[A case of spastic paraparesis, mental retardation and thinning of corpus callosum].
There are several reports of the patients who have peculiar clinical presentation, that is, spastic paraparesis, mental disturbance and thinning of corpus callosum. We presented a sporadic case with similar symptoms. He was born by normal vaginal delivery without problems from consanguineous parents. His development had delayed since his infantile period. He started to have spasticity of the legs at the age 13 years and it worsened with advancing age. On examination at age 19, he was mentally slow, his full-scale IQ being 35. The tone in the arms was slightly increased and marked in the legs. The finger to nose test caused mild dysmetria. Rest of the neurological examinations were normal. MRI demonstrated characteristic thinning of corpus callosum, dominant in anterior portion. In addition, it showed wide cavum vergae and cavum septi pellucidi, and abnormal high intensity in periventricular white matter. The findings of MRI were possibly suggestive of the static developmental disturbance of brain.
