pituitary region mass with intrinsic high T1 signal
Pituitary region mass with intrinsic high T1 signal, also referred as suprasellar hotspots, are relatively frequently encountered, and the presence of high T1 signal narrows the differential somewhat.
Differential diagnosis
The differential can be divided by the substance causing the T1 hyperintensity :
- blood
- hemorrhagic pituitary macroadenoma (with or without clinical pituitary apoplexy) (most common )
- thrombosed aneurysm
- fat
- postoperative fat packing
- teratoma / dermoid cyst
- lipoma
- protein
- calcification
- normal variant
- posterior pituitary bright spot
- normal posterior pituitary
- ectopic posterior pituitary
- normal anterior pituitary
- pregnancy
- first 3 months of life
- total parenteral nutrition
- posterior pituitary bright spot
