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. Radiological features of pituicytomas. a. The tumor is completely located in the intrasellar region. b. The tumor is located in the intrasellar-suprasellar region. c. 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
