Clinical question: Assess for pituitary adenoma. Signs and symptoms: Galacturia, irregular menses. Pre and post enhanced pituitary MRI:Examination demonstrates homogeneous signal intensity or pituitary gland on all nonenhanced images and measuring approximately 7.3 mm in height is within normal for patient of stated age of 26 years. Pituitary stalk is also normal in size and morphology. There is normal homogeneous enhancement of pituitary gland and pituitary stalk without detectable pituitary mass/adenoma. There is normal anatomical asymmetrical pneumatization of the sphenoid sinus with the right chamber being larger (with resultant mild elevation of the floor of the sella on the right) compared to left. There is normal signal intensity and morphology hypothalamus and without abnormal enhancement. There are normal bilateral cavernous sinuses and without abnormal enhancement. Bilateral Meckel's caves are also within normalThere is no abnormality at the level of the skull base and without abnormal enhancement.
1.No detectable pituitary lesion.2.Normal anatomic variation of asymmetric pneumatization of the sphenoid sinus sinus (R>L) results in mild inferior slanting of the floor of the sella to the left as detailed above.
