SATCHMO

The differential diagnosis of a suprasellar mass can be remembered through the SATCHMO mnemonic.

S - suprasellar/sellar adenoma, sarcoid
A - aneurysm, arachnoid cyst
T - teratoma
C - craniopharyngioma
H - hamartoma (of the tuber cinereum), hypothalamic glioma
M - meningioma
O - optic nerve glioma

The above image is from a patient who presented to the ER several times after multiple motor vehicle accidents. On clinical exam he was found to have visual field defects. NECT demonstrates a hyperattenuating sellar mass. Post operative diagnosis was pituitary macroadenoma.
