title: Metrizamide cisternography in pituitary and juxtapituitary lesions.
abstract: Seventy-five suprasellar metrizamide cisternograms were obtained, 25 in normal individuals who had had cervical myelography and 50 in patients with pituitary or juxtapituitary lesions. The technique accurately delineates a suprasellar extension of a small or moderate-sized pituitary lesion and usually shows its relationship to the optic chiasm. Large suprasellar masses, however, are not well visualized. 'Empty sellae' are readily demonstrated and have a high incidence in both normal individuals and those with pituitary tumors. This procedure can be supplemented by metrizamide CT cisternography and is simpler to perform and often better tolerated by patients than is pneumoencephalography.
