Clinical question: Change in tumor size. Signs and symptoms: Small pituitary tumor, elevated prolactin. Pre- and post enhanced pituitary MRI:Examination demonstrate mild leftward deviation of the pituitary stalk identical to prior exam. It demonstrate normal signal intensity and enhancement.There is homogeneous signal intensity of pituitary gland on all MRI sequences and including postenhanced series without convincing evidence of a detectable mass within the dictated. Deviation of pituitary stalk to the left however is suspicious for presence of a small intrapituitary mass/microadenoma. This examination is overall identical to prior study. The basal cistern and the suprasellar visual complex remains within normal. Bilateral cavernous sinuses are within normal. No detectable abnormality of the skull base or the sphenoid sinus is detected.
1.Subtle mass effect and deviation of the pituitary stalk to the left without convincing evidence of a defined pituitary mass/microadenoma.2.No evidence of any interval change since prior exam from an outside institution dated 6-30-14.3.Unremarkable pre and post enhanced pituitary MRI otherwise.
