Lissencephaly is in most cases a genetic anomaly of the brain development with agyria and/or pachygyria. It causes severe psychomotor retardation and epilepsy, which is often resistant to therapy. Some patients with type-I lissencephaly show cranial and facial dysmorphism and a deletion of chromosome 17p13.3 (Miller-Dieker syndrome). The isolated lissencephaly sequence occurs without these features. Patients with type-II lissencephaly present additional malformations of the posterior fossa and of the eyes (Walker-Warburg syndrome) and in some cases muscular dystrophy (cerebro-oculomuscular syndrome). Lissencephaly can be suspected with a high probability by its typical EEG. It is proved by imaging techniques. Therapeutic success is limited, the life expectancy is strongly reduced.

The authors report a case with Fukuyama type congenital muscular dystrophy (FCMD) and severe ocular abnormalities. Muscular dystrophy was confirmed by EMG, high muscle enzyme value and muscular biopsy. Computed tomography (CT) of the brain at 15 months of life showed mild central and cortical atrophy. Repeated CT scans at 22 and 32 months showed progressive character of the atrophy, with preservation of the cerebellar areas and the central grey matter only. Ophthalmologist examination revealed nystagmus, severe visual deficit, optic nerve atrophy and irregular color of the retina, especially in the peripheric areas. Electroretinography (ERG) was normal, cortically evoked visual responses (PEV) were absent. The association of congenital muscular dystrophy with brain changes and ocular abnormalities were found in FCMD, muscle-eye-brain disease (MEB) and Walker-Walburg syndrome (WWS). Our report, according to the recent literature, suggests that ocular lesions are caused by the same mechanism that provokes the central nervous system anomalies. It is probably of genetic origin: FCMD, MEB and WWS could be development abnormalities with a continual spectrum of disease severity.

We report five patients with Walker-Warburg syndrome. These patients showed congenital hydrocephalus, encephalocele, agyria, ocular abnormalities (cataracts in 100%), and in four signs of muscular dystrophy. No cause is known for theses abnormalities. Death occurred before two years of age; however, one patient is currently alive with 6 months of age. This disease is recognized as a genetically determined condition with an autosomal recessive mode of inheritance. We comment on the similarities of this syndrome with other syndromes and the latest investigations concerning the pathogenesis. We believe that it is very important to suspect this illness in order that genetic counseling can be offered.

We report 11 children with a homogeneous clinical syndrome affecting both sexes, characterized by weakness at birth, slowly improving course, weakness of all muscle groups, arreflexia, elevated blood creatine kinase, normal nerve conduction velocity, dystrophic changes on muscle biopsy, and diffuse periventricular cortical white-matter abnormalities with sparing of corpus callosum, internal capsule, and brain stem. We compare them to 48 other previously reported similar cases and designate them as altered myelin radiographic pattern congenital muscular dystrophy (CMD), which is the same as occidental CMD. We compare them to the other presently accepted phenotypes: progressive Fukuyama CMD, Walker-Warburg or cerebral-ocular CMD, and Santavuori or muscle-eye-brain CMD. We suggest that the different phenotypes are alleles of the same gene, which regulates or expresses a structural protein required for muscle integrity, myelination, and formation of the cortex. Such phenotypic diversity has been established for mutations of Xp21 in X-linked muscular dystrophies.

The Walker-Warburg syndrome (WWS) is a rare autosomal recessive disorder characterized by lissencephaly, cerebellar and retinal malformations, and congenital muscular dystrophy. We report a new case of WWS identified with the aid of cranial MR and briefly review the radiologic findings of this lethal syndrome.

A 20-week fetus affected with cerebro-ocular dysplasia and muscular dystrophy (Walker-Warburg Syndrome) is reported. The central nervous system (CNS) findings were typical of those previously described in this disorder, and were characterized by lissencephaly, hydrocephalus, and cerebral and cerebellar cortical dysplasia with glial and neuronal displacement into the leptomeninges. In addition, severe hypoplasia of pyramidal tracts were noted in the brain stem and spinal cord, as well as malformation of the inferior olivary and dentate nuclei. Skeletal muscle and eyes appeared normal on light microscopy. The genetic defect in this disorder is expressed in the CNS early during the first trimester and causes a marked disorder of cellular migration. Overt changes in muscle occur during a later period. The changes in the CNS are similar to, but more severe than, those found in Fukuyama congenital muscular dystrophy, and both may represent a failure of constraint of neuronal migration. Whether the syndromes characterized by cerebro-ocular dysplasia and muscular dystrophy are genetically heterogeneous or allelic variations is unknown. Molecular genetic analysis should elucidate this question.

Clincopathological features of Fukuyama type congenital muscular dystrophy (FCMD), a combination of brain malformation and muscular dystrophy with facial muscle and CNS involvement and high prevalence in Japan, are reviewed. Evidence of progressive dystrophy, negative correlations between muscle enzyme levels and age and CT numbers of muscle and age, are presented. Skeletal muscle histopathology is reviewed. Febrile illness-induced transient exacerbation of muscle weakness is reported. Characteristic brain malformations, e.g. micropolygyria, other dysgenesis, are reviewed. Their severity correlated with maximal mental and motor function. The etiology and significance of low density areas (LDA) in white matter on CT, possibly reflecting delayed or abnormal myelination, and ventricular dilatation are discussed. Spontaneous LDA improvement makes hydrocephaly unlikely. Ophthalmological differential diagnosis from Santavouri disease and Walker-Warburg syndrome, characterized by visual disturbance/glaucoma and microphthalmia/anterior chamber defects, respectively, is discussed. A single defective gene, manifesting as a metabolic error, may produce CNS and ocular defects as well as muscle degeneration in FCMD.

Walker-Warburg syndrome is a lethal, autosomal recessive disorder characterized by anomalies of the central nervous system and eye. Typical findings include hydrocephalus, agyria, retinal dysplasia, cerebellar dysgenesis, anterior chamber dysgenesis, and encephalocele. Recently, the phenotypic spectrum has been expanded to include congenital muscular dystrophy. Two sibs with Walker-Warburg syndrome are reported. One sib had congenital glaucoma and hydrocephalus. The other sib had hydrocephalus, microtia, absent auditory canals, and pale retinas, barely within the phenotypic spectrum of the disorder. Elevation of muscle enzymes was consistent with the diagnosis of Walker-Warburg syndrome.

We describe a child with Fukuyama type congenital muscular dystrophy (FCMD) who had several ocular manifestations since birth. These included high myopia, strabismus, nystagmus and optic atrophy of both eyes. Later he developed retinal detachment of both eyes. Our survey of 33 cases with FCMD revealed that high myopia and optic atrophy are common in FCMD. Retinal detachment was reported in two cases in addition to the present one and was considered to be of developmental origin. The association of congenital muscular dystrophy with brain changes and ocular anomalies were found in FCMD, muscle, eye and brain disease (MEB) and Walker-Warburg syndrome (WWS). Ocular manifestations in FCMD were, in general, less severe than those in WWS or MEB. Our study suggests that FCMD, MEB and WWS are developmental abnormalities with a continual spectrum of disease severity.
