Profound abnormalities of the brain were noted in a 6-year-old Japanese boy with congenital muscular dystrophy (CMD). Pathological alterations included diffuse cerebral and cerebellar micropolygyria, with bilateral temporal agyria, and abnormal fusion of gray matter in the basal portions of both frontal hemispheres. Microscopically, the architecture of both cerebral and cerebellar cortices was severely distorted, with irregular arrangement of neurons and increased vascularization. Skeletal muscles showed dystrophic changes rather than neurogenic atrophy. Eight autopsy cases of CMD with similar pathologic findings have been reported in Japan, although the lesions in the brain are quantitatively different from case to case. The findings indicate that CMD is a dysplastic disease of the central nervous system, with dystrophic involvement of skeletal muscles.

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.

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.

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.

Congenital muscular dystrophy (CMD) associated with cerebro-ocular dysplasia named muscle-eye-brain disease (MEB-D) is described in two sisters. Progressive hypotonia, mental retardation and severe visual failure appeared immediately after birth. Pathological examination demonstrated muscular dystrophy, hydrocephalus, type II lissencephaly and defective eye development of foetal origin. The great similarity of the clinical and neuropathological picture of both sisters is in agreement with an autosomal recessive inheritance. Neuropathological distinction between Fukuyama-CMD and MEB-D is a more severe and earlier cerebral developmental defect and the association with ocular dysplasia in MEB-D.

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.

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.

Walker-Warburg syndrome (WWS) is an autosomal recessive disorder manifest by characteristic brain and eye malformations. We reviewed data on 21 of our patients and an additional 42 patients from the literature. From this review, we expand the phenotype to include congenital muscular dystrophy (CMD) and cleft lip and/or palate (CLP), and revise the diagnostic criteria. Four abnormalities were present in all patients checked for these anomalies: type II lissencephaly (21/21), cerebellar malformation (20/20), retinal malformation (18/18), and CMD (14/14). We propose that these comprise necessary and sufficient diagnostic criteria for WWS. Two other frequently observed abnormalities, ventricular dilatation with or without hydrocephalus (20/21) and anterior chamber malformation (16/21), are helpful but not necessary diagnostic criteria because they were not constant. All other abnormalities occurred less frequently. Congenital macrocephaly with hydrocephalus (11/19) was more common than congenital microcephaly (3/19). Dandy-Walker malformation (10/19) was sometimes associated with posterior cephalocele (5/21). Additional abnormalities included slit-like ventricles (1/21), microphthalmia (8/21), ocular colobomas (3/15), congenital cataracts (7/20), genital anomalies in males (5/8), and CLP (4/21). Median survival in our series was 9 months. A related autosomal recessive disorder, Fukuyama congenital muscular dystrophy, consists of similar but less severe brain changes and CMD. It differs from WWS because of consistently less frequent and severe cerebellar and retinal abnormalities. We think that WWS is identical to "cerebro-oculo-muscular syndrome" and "muscle, eye, and brain disease."
