Enlarged cisternae magnae and posterior fossa cysts simulating Dandy-Walker syndrome on computed tomography

Radiology. 1978 Jun;127(3):681-6. doi: 10.1148/127.3.681.

Abstract

Computed tomography was performed on 5 children with posterior fossa cystic abnormalities. On an axial tomogram, an enlarged cisterna magna could not be distinguished from a Dandy-Walker variant, nor could an encysted fourth ventricle be distinguished from a subarachnoid cyst. Supplementary air encephalography or sagittal reconstruction of tomograms is necessary to define posterior fossa cysts accurately.
