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.
