Granulomatous hypophysitis due to Wegener's granulomatosis.
We describe the MR image findings in a case of granulomatous hypophysitis due to Wegner's granulomatosis. A high index suspicion of hypophysitis based on imaging findings allowed successful medical management and helped avoid surgery. The MR imaging features included a thickened stalk, a diffusely and uniformly enlarged gland, a normal size or minimally enlarged sella, and enhancement of the optic chiasm.
