Pituitary microadenoma: a radiological-surgical correlative study.

In this study, the authors evaluated the correlation between the radiological changes in the sella (using thin-section, complex motion tomography) and the location of pituitary microadenomas at surgery. A significant discrepancy was noted between the tomographic and surgical location of the tumor in 14 of 55 patients. The authors caution about absolute reliance upon tomography for making the diagnosis of pituitary microadenoma in a given patient.
