Fig. 75.1 Postoperative pituitary abscess. (a) Sagittal T1-weighted gadolinium-enhanced MR image. (b) Coronal T1-weighted gadolinium-enhanced image. A peripherally enhancing lesion in the sella displaces the pituitary stalk superiorly. The wall…
Fig. 8.1 Sagittal T1-weighted image without contrast. (1) clivus; (2) pons; (3) third ventricle; (4) sphenoid sinus; (a) anterior pituitary gland; (p) posterior pituitary gland; asterisk indicates pituitary stalk Fig….
Fig. 53.1 Mucocele. Coronal T1-weighted precontrast MR image. The sphenoid is expanded and contains T1-hyperintense material. The normal pituitary gland is seen superior to the expanded sinus Fig. 53.2 Mucopyocele….
Fig. 71.1 Basilar impression/invagination. (a) Sagittal T1-weighted precontrast MR image. (b) Sagittal CT image. The clivus is hypoplastic, and there is incomplete segmentation of C2 and C3. The odontoid process…
Fig. 9.1 (a) Sagittal T1-weighted image post gadolinium contrast enhancement. (b) Coronal T1-weighted image post gadolinium contrast enhancement. The pituitary gland exhibits homogeneous enhancement with a convex upper margin and…
Fig. 69.1 Duplication of the pituitary gland. (a) Sagittal T1-weighted MR scan shows hypothalamic thickening (arrow). (b) Coronal T1-weighted MR scan shows two separate anterior and posterior pituitary glands with…
