The technique of peri-hypophyseal phlebography is briefly described and the theoretical bases that inspire its utilizations and indications are pointed out. On the basis of 20 preliminary cases, the main applications of this investigation are illustrated, with a particular attention concerning the early diagnosis of lesions too small or too dishomogeneous to be detected with certainly on CT (i.e. intrapituitary microadenomas smaller than 5 mm; associated intrasellar lesions as empty sella + pituitary tumor).

CT in the diagnosis of sellar and parasellar lesions.

The Authors review their recent experience in investigating 185 cases of sellar and parasellar lesions, using as preliminary procedure stratigraphy and CT; further examinations were performed only in cases with unclear diagnosis. Their data confirm the reliability of this non-invasive protocol that allowed the detection of pathological changes in nearly 95% of cases and was able to define with certainty the nature of the lesions in over 72% of cases. However, other investigations were performed in 116 cases (63%): in 57 (31%) for diagnostic purpose, in 59 (32%) as complementary pre-operative studies.
