cystic pituitary region mass

MRI of a benign pituitary cyst. Pituitary cysts are not rare and if large enough they can cause symptoms by compression of the pituitary gland or suprasellar structures.

Magnetic resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Pars intermedia cyst. Sagittal T1WI (a) and axial T2WI (b) shows a small cyst between the anterior and posterior pituitary which lacks contrast enhancement on axial fat-suppressed T1WI (c)

Magnetic resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Epidermoid. Sagittal T1WI (a) shows an extra-axial lesion along the endocranial surface which has heterogeneous mostly low-intermdiate signal, and on T2WI has high signal (b). Diffusion-weighted imaging (DWI) (c) shows restricted diffusion

Magnetic resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Arachnoid cyst. Sagittal T1WI (a) and coronal T2WI (b) show a well defined cystic mass with low T1 and high T2 signal intensity with sellar and suprasellar components

Magnetic resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Cavernous malformation: coronal T2WI (a) and axial gradient echo (GRE) (b) images in a 5-year-old girl show a large suprasellar lesion with mixed low, intermediate and high signal intensity with a thin rim of low signal on T2WI and foci of low T2* signal from susceptibility effects of blood products on GRE

Magnetic resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Rathke’s cleft cyst. Sagittal T1WI (a) shows a lesion in the central portion of the pituitary gland which has high signal. Post-contrast sagittal fat-suppressed T1WI (b) shows lack of enhancement of the Rathke cleft cyst. The cyst has intermediate signal on T2WI (c) secondary to slightly elevated protein content
