Computed tomography of infratentorial masses in children

Seventeen cases of infratentorial mass lesions (excluding abscesses) in children are reviewed. The findings after computed axial tomography (CAT) are described, as well as the changes that were revealed by plain radiographs of the skull. Ancillary investigations were performed in 11 cases, and their usefulness is assessed. The possibility of making a provisional diagnosis of the nature of the lesion based on CAT findings is discussed
