[The value of cranial computed tomography in posterior fossa epidermoids and dermoids (author's transl)]

Report on posterior fossa epidermoids and dermoids (3 in the cerebellopontine angle, 1 in the region of the fourth ventricle). Computed tomographic aspects are related with other neuroradiological findings. Differential diagnosis of these mass lesions is discussed in detail, especially of low density and (rarely occuring) high density epidermoids.
