Pituitary microadenoma: a radiological-surgical correlative study

Area of Science:

• Neurosurgery
• Radiology
• Endocrinology

Background:

• Pituitary microadenomas require precise localization for effective surgical planning.
• Tomographic imaging is a common method used to assess sellar changes and guide surgical approaches.

Purpose of the Study:

• To evaluate the correlation between radiological findings in the sella and the surgical location of pituitary microadenomas.
• To assess the diagnostic accuracy of tomography in identifying pituitary microadenoma locations.

Main Methods:

• Utilized thin-section, complex motion tomography to examine the sella.
• Correlated tomographic findings with the actual intraoperative location of pituitary microadenomas in 55 patients.

Main Results:

• A significant discrepancy between tomographic and surgical tumor location was observed in 14 out of 55 patients (approximately 25%).
• This indicates limitations in the precision of tomographic imaging for pinpointing microadenoma sites.

Conclusions:

• Radiological assessment of the sella using tomography may not always accurately reflect the surgical location of pituitary microadenomas.
• Clinicians should exercise caution and not rely solely on tomographic data for diagnosing and localizing pituitary microadenomas.
