Clinical question: History of pituitary adenoma status post resection x 2. Signs and symptoms: Surveillance scan. Pre-and post enhanced pituitary MRI:There is a focus of residual pituitary adenoma on the right side of sella which measures nearly identical to prior exam in all measurements. It measures approximately 11 mm in transverse axis on coronal post enhanced series and 8.2-mm in height on coronal post enhanced series of current exam and on remeasurement of prior to study. It measures approximately 11.5 to 13.7-mm in AP axis on sagittal post enhanced series fairly similar to prior exam. This finding result in slight elevation of diaphragmatic sella similar to prior study. The rightward deviated pituitary stalk terminates superiorly to the right of midline similar to prior exam. Deviation of pituitary stalk is likely a post treatment change and scarring. There is no evidence of a mass on the left side of pituitary.The suprasellar visual complex appears thin however remains identical to prior study and without abnormal enhancement.
Residual adenoma on the right side of pituitary gland remains stable in size, signal and pattern of enhancement since prior study.
