Abstract
We prospectively evaluated the magnetic resonance (MR) images of 28 sellar
and juxtasellar lesions which were obtained using a 2.0T superconducting MR system and
compared them with computed tomography (CT) scans. A variety of lesions were included: 14
pituitary adenomas; three germ cell tumors; two each of meningioma and empty sella; and
one each of craniopharyngioma, teratoma, epidermoid, trigeminal neuroma, nasopharyngeal
cancer with parasellar extension, tuberculoma and carotid cavernous fistula (CCF). MR more
clearly demonstrated the relation of the lesions with the optic chiasm, infundibular stalk,
carotid arteries, 3rd ventricle and cavernous sinus. Carotid and cavernous vascular structures
were better evaluated with MR, and angiography may be avoided in some cases. MR enabled
characterization of lesions containing hemorrhage, fat and flowing blood, and allowed more
specific diagnoses than CT in hemorrhagic tumor and CCF. MR was equivalent to CT in
detecting the lesions, even though most of the homogeneously enhancing tumors on CT
including pituitary adenomas, meningiomas, germ cell tumors, tuberculoma, etc, revealed
isointensity signal on MR. CT was more sensitive than MR for detecting calcification and
sella- floor erosion.
