Classical signs and appearances in pediatric neuroradiology: a pictorial review.

Atalar MH, Salk I, Egilmez H - Pol J Radiol (2014)

Bottom Line: Radiological practice includes classification of illnesses with similar characteristics through recognizable signs.In this report, twenty-eight important and frequently seen neuroradiological signs in childhood are presented and described using X-rays, computed tomography (CT), magnetic resonance (MR) images, illustrations and photographs.

f24-poljradiol-79-479: Axial T2-weighted MRI at the level of the posterior fossa showing antero-posterior elongation of the fourth ventricle giving it a “diamond shaped” appearance (arrows).

Mentions: This appearance is seen in rhombencephalosynapsis. Rhombencephalosynapsis is a rare condition with most cases found in newborns and infants. Morphological findings are predominantly characterized by fusion of the cerebellar hemispheres and absence of the vermis, often accompanied by supratentorial anomalies. The size of the fourth ventricle is variable and in its axial plane it usually has a “keyhole or diamond shape” (Figure 24). This appearance is a result of dorsal and rostral convergence of the dentate nuclei, cerebellar peduncles and inferior colliculi [28].
