Magnetic
resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Pilomyxoid astrocytoma in a 4-month-old baby girl. Sagittal T1WI (a) shows a large hypothalamic lesion with intermediate signal which extends superiorly into and filling the third ventricle, and inferiorly into the suparsellar cistern. The tumour has mostly high signal on axial T2WI (b)

Clinical
features, radiological profiles, pathological features and surgical outcomes of pituicytomas: a report of 11 cases and a pooled analysis of individual patient data.

The tumor is completely located in the suprasellar region. d. Pituicytoma invading the right cavernous sinus. The lesion surrounded the internal carotid artery, and the optic chiasm was not compressed. e. The optic chiasm was oppressed and elevated by the tumor, and the cavernous sinus was not involved. f. Pituicytoma invading the right cavernous sinus; the optic chiasm was compressed, and the tumor was accompanied by cystic degeneration

Pituitary tumors, in other words, tumors which arise from the pituitary gland itself, include:
- pituitary adenoma
- pituitary carcinoma
- pituicytoma
- pituitary metastases
- spindle cell oncocytoma (rare)
- pituitary blastoma
Often the term is used more broadly to refer to pituitary region masses.
