Clinical question: History of pituitary microadenoma, evaluate for interval change. Signs and symptoms: None. Pre and post enhanced pituitary MRI:Examination redemonstrated a hypoenhancing pituitary microadenoma on the left and with subtle extension across the midline to the right within the pituitary gland. It measures 8.6 x 6.6 mm in size (measuring on coronal postenhanced series 801 image 8). Although when compared with prior exam the craniocaudad axis is minimally larger from prior measurements of 6 mm it cannot be confirmed with certainty on sagittal post enhanced series which measures nearly identical to prior exam. There is subtle elevation of the diaphragmatic sella however without extension into the basal cistern. Pituitary stalk remains in midline and with normal size and pattern of enhancement. Bilateral cavernous sinuses are also remain normal in signal intensity and pattern of enhancement.
Stable pituitary microadenoma as detailed above. Please see comments.
