The CT features of cerebellar lesions with von Hippel-Lindau's disease are analyzed. The use of CT scanning for associated spinal hemangioblastomas is discussed in the light of a case with a low cervical lesion. The role of computed tomography in the neuroradiological investigations is discussed. [ABSTRACT FROM AUTHOR]

The use of coronal tomograms for CT scanning of the orbits is emphasized and the technic for patient positioning is described. Normal tomographic images are described and the contribution of coronal scans to a correct diagnosis is stressed in the light of 16 pathological cases. Coronal tomograms are especially valuable to show the regions of the orbital floor and roof and complement axial scanning. [ABSTRACT FROM AUTHOR]

Bilateral visual impairment, associated with amenorrhea, diabetes insipidus and mental deterioration were observed in a 28 year old woman. CT scan revealed bilateral symmetrical infiltrative processes surrounding the ventricular system, which was confirmed by postmortem examination. Histologicaly the lesion was a germinoma.

The images obtained by computed tomography constitute a new and interesting approach to lesions of the craniovertebral region. The criteria of basilar invagination must be systematically checked in routine examination. The main interest of CT scanning is the simultaneous view of the bony structures as well as the central nervous system in a completely innocuous way. [ABSTRACT FROM AUTHOR]
