 The exam was not performed as a pituitary MRI which somewhat limits evaluation. In addition, there is mild motion degradation of the images. Within these limitations, there is an enhancing pituitary mass measuring 19 CC x 16 ML x 17 AP mm with effacement of the suprasellar cistern, abutting the optic chiasm without significant displacement or mass effect on the optic chiasm. Although evaluation of the cavernous sinuses is limited, the mass appears to the confined within the sella, abutting the cavernous and supraclinoid internal carotid arteries without clear invasion. There are no other areas of suspicious intracranial enhancement. There is no acute infarct, or midline shift. There is patchy T2 signal abnormality adjacent to the trigone of the left lateral ventricle without enhancement, nonspecific, possibly vascular related. There is no hydrocephalus.
19 x 16 x 17 mm enhancing pituitary mass most likely representing a macroadenoma. Metastatic disease is considered much less likely.No additional intracranial lesions are seen to suggest metastatic disease.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
