Pituitary blastomas are a very rare type of pituitary tumor.
Pituitary blastomas typically affect children under 2 years old. They are almost pathognomonic for DICER1 syndrome and warrant testing for germ-line DICER1 mutation if found 1,2.
Few cases of imaging findings have been reported, but they can present as small solid pituitary masses or large cystic and solid masses with suprasellar and cisternal extension.
