Overview
Based on size, a prolactinoma can be classified as a microprolactinoma (<10 mm diameter) or macroprolactinoma (>10 mm diameter).
Classification
Prolactinoma may be classified based on either size or location.
Based on size
A prolactinoma can be classified as
- microprolactinoma (<10 mm diameter)
- macroprolactinoma (>10 mm diameter)
Based on location
The classification for pituitary adenomas is as follows:
- 0: Normal pituitary appearance.
- I: Enclosed within the sella turcica, microadenoma, smaller than 10 mm
- II: Enclosed within the sella turcica, macroadenoma, 10 mm or larger
- III: Invasive, locally, into the sella
- IV: Invasive, diffusely, into the sella
The grading schema for suprasellar extensions is as follows:
- A: 0 to 10 mm suprasellar extension occupying the suprasellar cistern
- B: 10 mm to 20 mm extension and elevation of the third ventricle
- C: 20 mm to 30 mm extension occupying the anterior of the third ventricle
- D: A larger than 30 mm extension, beyond the foramen of Monro, or Grade C with lateral extensions[1]
