visual field loss left side history of pituitary cyst "collapsed" There is no evidence of intracranial hemorrhage, mass, or acute infarct. Punctate T2 hyperintense foci in the left periventricular white matter and right corpus callosum are not significantly changed. There is no abnormal intracranial enhancement. Ventricles and sulci are prominent for age suggesting volume loss. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.A 2 mm lesion which is hypoenhancing and hypointense on T2 is more evident on this exam but was likely present on prior exams accounting for differences in technique. There is an additional 3 mm T2 hyperintense focus more posteriorly and superiorly which is unchanged from the prior exams. Please note that this lesion is not seen on current dynamic images as it is not included within the slices sampled. Pituitary size and shape otherwise appears normal. Pituitary stalk appears normal. No significant mass effect on the chiasm.
1.No findings to explain visual field deficit.2.A 2 mm lesion which is hypointense on T2 and hypoenhancing is unchanged from prior exams accounting for differences in technique and may represent a remnant pars intermedia cyst or other incidental pituitary cyst.3.A 3 mm T2 hyperintense focus within the pituitary is unchanged from prior exams and may represent a cystic microadenoma or another incidental pituitary cyst.4.Stable minimal white matter changes within the brain.
