CT scan is able to show cerebral atrophy more safely and more easily than pneumo-encephalography or cerebral angiography. Then, various methods have been reported for quantitative analysis of cerebral atrophy on CT scan. Generally, cerebral atrophy might be judged from the ventricular dilatation with some indices, calculated from various ventricular width. But, there is no general agreement on what index is the most reliable. In this paper, we attempted to establish the index, easy to measure and most reliable. Our method is as follow. Method. We carried out the CT scan (EMI 1010) on 89 neurologically intact patients. Scans were parallel to orbito-meatal line (OML), and were 10 mm in thickness. On CT scan films, various width, area of anterior horns and area of bodies of lateral ventricles were measured (Fig. 1). Measurement about the anterior horns of lateral ventricles were carried out on image the most clearly showed the foramen of Monro. And measurements about the bodies of lateral ventricles were on image, 20 mm above the image of anterior horn. Correlations of various width and areas were calculated (Table 1). Then we proposed new indices with high correlations (over 0.9) with ventricular area; Anterior horn CVI (Cerebro-Ventricular Index) and Body CVI (Fig. 2, 3). Patients with myotonic dystrophy show cerebral atrophy. We carried out the CT scan (GE-CT/T 8800) on 17 myotonic dystrophy patients and 30 controls. Between the two groups, age and sex were almost matched (Fig. 4).(ABSTRACT TRUNCATED AT 250 WORDS)

Two autopsy cases of congenital muscular dystrophy of Fukuyama type (F-CMD) were described. The first case was diagnosed clinically and pathologically as its typical case. Neither his family history nor the history of his prenatal period were contributory. He had suffered from muscle weakness and atrophy since his birth. Serum CPK was markedly elevated. EMG and muscle biopsy proved dystrophic changes of the skeletal muscles. In addition, he manifested mental retardation and attacks of convulsion. EEG failed to elicit remarkable changes, but PEG represented ventricular dilatation. He died of respiratory insufficiency at age 12. His postmortem examination showed variegated anomalies in the nervous system. Extensive micropolygyria was present in the cerebrum and cerebellum accompanied by adhesions between the bilateral cerebral hemispheres. Assymmetry of the longitudinal fibers was pointed out in the pontine base. Anterior horn cells were atrophic and moderately depopulated. On the other hand, the second patient was an atypical F-CMD case in symptoms, signs and pathology. His grand-mothers on both father's and mother's sides wee first cousins. His three siblings showed no similar disorders. His mother developed slight gestational toxicosis in the sixth and seventh months of pregnancy. His muscle weakness, contracture of the bilateral hip-joints and clubfoot had been observed since his birth. Physical and neurological examinations at age 6 showed deformity of the skull, myopathic face, macroglossia, high-arched palate, pigeon chest, scoliosis of the thoracic spine. In addition, generalized muscular atrophy, hypotonia and areflexia were recognized. Pseudohypertrophy of the muscles was absent. Sensation was intact to all modalities. Serum CPK and LDH were moderately increased.(ABSTRACT TRUNCATED AT 250 WORDS)
