cleft cyst in a 53-year-old man with a pituitary adenoma and acromegaly

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)

Teenager with

hyperprolactinemia. Sagittal (above) and coronal (below) T1 MRI with contrast of the sella shows a small mass in the midline of the sella that enhances less than the surrounding pituitary gland.The diagnosis was pituitary microadenoma.

Spindle cell

oncocytoma of the adenohypophysis in a woman: a case report and review of the literature. (A) Coronal magnetic resonance imaging studies showing a sellar mass with suprasellar extension but no invasive growth (arrow). (B) T1-weighted image showing the enhancement of the mass (arrow).

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

A rare case

of pituicytoma-related hypercortisolism in a patient with Cushing syndrome—case report. MRI T1-weighted sagittal view of non-enhancing 0.46 × 0.33 cm focus of low signal in the left central portion of the pituitary gland on the post-contrast

A rare case

of pituicytoma-related hypercortisolism in a patient with Cushing syndrome—case report. MRI T1-weighted coronal view same non-enhancing 0.46 × 0.33 cm pituitary lesion

A rare case

of pituicytoma-related hypercortisolism in a patient with Cushing syndrome—case report. MRI T1-weighted coronal view same non-enhancing 0.46 × 0.33 cm pituitary lesion and an arrow indicating the thickening of the pituitary stalk

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Glioma in a 2-year-old girl with neurofibromatosis type 1. Sagittal (a) and axial (b) post contrast T1WI shows a partially enhancing lesion enlarging the optic chiasm and proximal optic nerves

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Teratoma. Sagittal T1WI (a) and axial T2WI (b) show a lesion at the undersurface of the hypothalamus which has mixed low, intermediate and high signal. Axial CT image (c) shows the lesion to contain zones of calcification, fat and intermediate soft-tissue attenuation

Teenager with

short stature. Sagittal (above) and coronal (below) T1 MRI with contrast of the sella shows a large homogenous solid mass arising in the sella and extending superiorly into the suprasellar region that shows homogenous enhancement with contrast.The diagnosis was pituitary macroadenoma.

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Germ cell tumours in two different children. Post-contrast T1WI (a) shows a large enhancing lesion in the suprasellar cistern extending superiorly into the third ventricle and posteriorly into the prepontine cistern. Sagittal post-contrast T1WI (b) in another child shows enhancing, disseminated germ-cell tumour in the suprasellar cistern, third and lateral ventricles, with involvement of the corpus callosum and optic chiasm

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Enthesioneuroblastoma. Sagittal T1WI (a) and post-contrast T1WI (b) show a destructive mass lesion involving the sphenoid bone which invades the sphenoid sinus and sella. The tumour shows prominent, mildly heterogeneous contrast enhancement

Extraventricular

neurocytoma of the sellar region: case report and literature review. The pre- and post-operative MRI. a–d Preoperative MRI showing a intrasellar and suprasellar tumor extending to anterior skull base and superior clivus. e, f The postoperative enhanced MRI showing subtotal tumor removal, with a little tumor remained in the intrasellar region
