[CT of the sella following hypophyseal surgery].
A CT control scan of 32 patients after transsphenoidal resection of a pituitary tumour revealed sellar contents of different density and varying extent. Additional criteria were used to differentiate the intrasellar structures (size, extent, shape, structure, contrast enhancement, bone changes). CT made the definite diagnosis in 6 patients with pituitary tumour recurrence. Hormonal measurements were superior to CT in identifying recurrent tumours in another 3 patients. It is concluded that hormonal methods should be used in evaluating patients after surgery of a hormone-producing tumour. However, CT is the most useful method in detecting tumour recurrence in patients with non-functioning adenomas, and, if an adequate technique is used (coronal scanning, iv-contrast), even clinical asymptomatic tumours can be identified.
