Short Report - Rhombencephalosynapsis: CT and MRI findings
Mendonça JLF, Natal MRC, Viana SL, Coimbra PPA, Viana MACB, Matsumine M
Abstract
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 high spatial and contrast resolution increased its recognition. Two cases are reported, with emphasis on imaging findings.
