Last revised by Arlene Campos on 19 Jan 2024

Useful mnemonics for remembering the differentials for pituitary region masses (in addition to macroadenoma) are:

  • SATCHMO/STOMACH 1,2

  • MOuSTACHE

  • SOME ACTH HORMONE

Mnemonics

SATCHMO/STOMACH 

Some prefer adding an E at the end and moving 'histiocytosis' to this last letter as:

Some prefer to reorder the mnemonic to spell 'STOMACH' instead.

MOuSTACHE
SOME ACTH HORMONE

History and etymology
