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

SATCHMO
MOuSTACHE
SOME ACTH HORMONE

Mnemonics

SATCHMO

S: sarcoid
A: aneurysm
T: teratoma or tuberculosis (and other granulomatous diseases)
C: craniopharyngioma, cleft cyst (Rathke), chordoma
H: hypothalamic glioma, hamartoma of tuber cinereum, histiocytosis
M: meningioma, metastasis
O: optic nerve glioma

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

E: eosinophilic granuloma or epidermoid/dermoid/teratoma

MOuSTACHE

M: meningioma, metastasis
O: optic nerve glioma
S: sarcoidosis, sellar tumor (pituitary adenoma)
T: teratoma or tuberculosis (and other granulomatous diseases)
A: aneurysm
C: craniopharyngioma, cleft cyst (Rathke), chordoma
H: hypothalamic glioma, hamartoma of tuber cinereum.
E: eosinophilic granuloma or epidermoid/dermoid/teratoma

SOME ACTH HORMONE

History and etymology

As the word Satchmo is best known as the nickname of Louis Armstrong, it is probably best to omit the ending E, especially as the term histiocytosis is preferred to eosinophilic granuloma.
