Vision loss, history of pituitary tumor Examination is motion degraded. There is however no appreciable change in heterogeneously enhancing tissue involving the sella, extending greater on the left than the right, and measuring approximately 21 mm in the transverse dimension, 11 mm in the craniocaudal dimension (on the left), and up to 20 mm in the AP dimension(on the left). These measurements are unchanged. As before, lesion extends to abut the left cavernous sinus without clear evidence of invasion. Areas of T2 hyperintensity are again seen and unchanged. The pituitary stalk deviate towards the right also unchanged. No significant extension into the suprasellar cistern. No mass effect on the optic chiasm. Mass approximates the left prechiasmatic optic nerve in its anterosuperolateral aspect similar to prior without mass effect.Limited views of the brain demonstrate diffuse parenchymal volume loss including the bilateral hippocampi. Mild periventricular T2 hyperintensity likely representing small vessel ischemic changes are again seen.
No significant change in size or appearance of the residual pituitary adenoma. No mass effect in the optic chiasm. Mass comes close to the left prechiasmatic optic nerve in its anterosuperolateral aspect similar to prior without mass effect.
