We report three patients with slowly progressive spastic paraplegia and dementia; MRI on these patients revealed hypoplasia of the corpus callosum. The mode of inheritance was supposed to be autosomal recessive. Patient 1 (26-year-old man) is an elder brother of patient 2 (21-year-old man). Their parents are first cousins. Patient 3 (woman), a sporadic case, died of pneumonia at the age of 44. Their motor development after the birth was normal, but patient 3 was mildly mentally retarded.
Gait disturbance
due to spastic paraplegia developed at the age of nine (patient 2), fifteen (patient 1) and nineteen (patient 3), respectively. They also showed slowly progressive mental deterioration. Patient 1 has also suffered from mild amyotrophy and sensory disturbance in the distal part of the extremities since the age of 25. Patient 3 was bed-ridden at the middle of her thirty's because of generalized amyotrophy and sensory disturbance in addition to spastic quadriplegia and profound dementia. Their MRI reveal the
thinning
of the corpus callosum. We think the
thinning
must be hypoplasia of the corpus callosum, because the cerebrum showed normal appearance on MRI in patient 1 and patient 2. These clinical findings and imaging studies are essentially similar to those of the cases reported by Iwabuchi et al (1991). We propose autosomal recessive HSP associated hypoplasia of the corpus callosum as a new type of HSP.

We report an autopsy case of a 51-year-old man clinically diagnosed with a complicated type of hereditary spastic paraplegia. His sister showed similar manifestations.
Gait disturbance
was manifested at 14 years of age. Subsequently, slowly progressive spastic tetraplegia developed with mental deterioration, neuropathy and amyotrophy. Marked cerebral atrophy with thin corpus callosum was shown by cranial MRI. Autopsy revealed a severely atrophic brain with extreme
thinning
of the whole corpus callosum. Microscopically, neurodegeneration was found in the corticospinal tract, thalamus, cerebral white matter and substantia nigra, as well as in the anterior horn and posterior column of the spinal cord. The remaining neurons contained large amounts of lipofuscin and eosinophilic granules. Unique to this patient was the severe gliosis in the cerebral white matter and substantia nigra, suggesting that sufficient development had been established when the degenerative process occurred. The predominant feature of the present case is the neurodegeneration process rather than hypoplasia.
