There is a large lobulated suprasellar mass (measuring 65 x 45 x 35 mm) centered on the optic chiasma and hypothalamic region, extending to the sellar region, optochiasmatic and interpeduncular cisterns as well as the anterior portion of the 3rd ventricle and cavernous sinuses. It elicits a low signal on T1, high signal T2 with vivid homogeneous enhancement on postcontrast sequences. A mass effect is noted on the midbrain and temporal lobes. No significant obstructive hydrocephalus is seen.
Case Discussion
MRI features of a large enhancing suprasellar soft tissue mass centered on the optic chiasma and hypothalamic region most consistent with a chiasmatic-hypothalamic glioma.
