Clinical question: Follow-up. Signs and symptoms: None. Pre-and post enhanced pituitary MRI:Examination redemonstrates a previously known pituitary microadenoma in the right paramedian inferior pituitary. There is interval decreased size of microadenoma since prior exam. It measures approximately 4.6 mm in transverse axis coronal T2-weighted images compared to prior study measurements of 7.3-mm. The lesion demonstrates no enhancement and on post enhanced images measures approximately 4.9 mm compared to prior study measurements of 6.6-mm. Decreased size results in decreased superior bulge of the pituitary gland. The pituitary stalk remains in midline and with normal pattern of enhancement. The basal cistern and the suprasellar visual complex are unremarkable. Bilateral cavernous sinuses and the straight normal signal intensity and pattern of enhancement.
1.Interval decreased size of patient's known pituitary microadenoma as detailed/measured above.2.Interval decreased superior bulge of pituitary gland secondary to decreased size of microadenoma.3.Unremarkable exam otherwise.
