Neoplasm of unspecified behavior of brain [D49.6] / Benign neoplasm of pituitary gland [D35.2], Reason for Study: ^Reason: pituitary adenoma, 6 month follow up eval for changes History: 6 month follow up No evidence of acute ischemic or hemorrhagic lesion.There are pituitary macroadenoma sized about 32.3mm x 40.3mm on sagittal post contrast scan, unchanged since prior scan. The MR characteristics do not show any interval change either.Right frontal craniotomy is again seen with underlying encephalomalacia unchanged. Multiple meningiomas including tentorial based left occipital location, right frontal convexity, left anterior sylvian fissure area, and anterosuperior aspect of the falx, do not show any interval change in terms of size, configuration and MR characteristics since prior scan. The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.Pituitary Gland MRIPost transsphenoid surgery status.There is a large pituitary gland mass which does not show any interval change in terms of size, configuration and MR characteristics since prior scan.In particular, there is no change regarding suprasellar and bilateral cavernous sinus extensions since prior scan.There is no midline shift or herniation.The suprasellar cistern, optic chiasm, hypothalamus, and cavernous sinuses are unremarkable. Slightly diminutive optic chiasm and bilateral optic nerves indicating atrophic changes are again seen, unchanged.
1. Post right frontal craniotomy and post transspehnoidal surgery status.2. No change of multiple meningiomas and pituitary macroadenoma since piror scan.3. Slightly atrophic both optic chiasm and bilateral optic nerves, unchanged.
