Overview

Prolactinoma can be classified based upon either size or local invasion. 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 local invasion.

Classification based on size

Based on size, a prolactinoma can be classified as:

  • Microprolactinoma (<10 mm diameter)
  • Macroprolactinoma (>10 mm diameter)

Classificatioin based on local invasion[1][2][3]

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 scheme for suprasellar extensions is as follows:
