Rhombencephalosynapsis: a hindbrain malformation associated with incomplete separation of midbrain and forebrain, hydrocephalus and a broad spectrum of severity.
Rhombencephalosynapsis is a midline brain malformation characterized by missing cerebellar vermis with apparent fusion of the cerebellar hemispheres. Rhombencephalosynapsis can be seen in isolation or together with other central nervous system and extra-central nervous system malformations. Gómez-López-Hernández syndrome combines rhombencephalosynapsis with parietal/temporal alopecia and someti...
متن کاملPartial rhombencephalosynapsis.
We describe an infant in whom partial rhombencephalosynapsis was diagnosed by using MR imaging. The anterior vermis and nodulus were normally developed, but part of the posterior vermis was deficient. There was partial fusion of the hemispheres in the inferior part of the cerebellum. Partial rhombencephalosynapsis is described for the first time, and our findings support the recent embryologic ...
متن کاملRhombencephalosynapsis: cerebellar embryogenesis.
We describe two infants in whom rhombencephalosynapsis was diagnosed with MR imaging in vivo. In contrast to Dandy-Walker malformation, the vermian maldevelopment in this anomaly is characterized by an absence of the anterior vermis and a deficiency of the posterior vermis. The cerebellar hemispheres are fused. In an attempt to identify the pathogenesis of these anatomic manifestations, we ques...
متن کاملRhombencephalosynapsis: CT and MRI findings.
An unusual disorder of cerebellar development, rhombencephalosynapsis is a unique entity which presents with cerebellar fusion and absence of cerebellar vermis on imaging studies, often associated with supratentorial findings. No specific clinical syndrome has been described in these patients so far, and most cases are found in infancy and childhood. MRI and its multiplanar capabilities and hig...
متن کاملRhombencephalosynapsis associated with hand anomalies.
A case of rhombencephalosynapsis, a very rare disorder characterized by agenesis or hypogenesis of the cerebellar vermis and fusion of the cerebellar hemispheres, is reported with magnetic resonance imaging features. Radiographs showed anomalies in both hands; namely phalangeal hypoplasia and occult polydactyly in the right hand and syndactyly in the left, previously unreported in association w...
