zystische Läsionen in der Hypophyse

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. Pituitary adenomas. Sagittal post-contrast fat-suppressed T1WI (a) shows an heterogenously enhancing pituitary macroadenoma which contains a non-enhancing portion with high signal on T2WI (b). secondary to cystic degeneration. Coronal post-contrast fat-suppressed T1WI (c) shows a pituitary microadenoma which shows less early contrast enhancement than the normal pituitary tissue
