Summary
Fractionated encephalography, particularly frontal tomograms, aids in diagnosing small pituitary prolactin-secreting adenomas. These imaging techniques reveal sellar diaphragm bulging and pituitary stalk deviation, crucial for accurate detection.
Area of Science:
- Neurology
- Radiology
- Endocrinology
Background:
- Pituitary adenomas, specifically prolactin-secreting types, present diagnostic challenges.
- Sellar changes can be subtle, especially in smaller adenomas.
Purpose of the Study:
- To describe sellar and encephalographic changes in pituitary prolactin-secreting adenomas.
- To evaluate the diagnostic utility of fractionated encephalography in detecting small adenomas.
Main Methods:
- Retrospective analysis of 75 cases of pituitary prolactin-secreting adenomas.
- Utilized sellar imaging and fractionated encephalography, including frontal tomograms.
Main Results:
- Encephalography demonstrated lateral bulging of the sellar diaphragm.
- A contralateral shift of the pituitary stalk was observed in cases with smaller adenomas.
Conclusions:
- Fractionated encephalography is valuable for diagnosing small pituitary adenomas.
- Frontal tomograms are particularly effective in identifying subtle sellar changes indicative of adenoma.
