Imaging studies. (a) MRI of pituitary adenoma – T1 weighted sagittal MRI of the pituitary gland after intravenous contrast reveals an enlarged gland that is centrally hypoenhancing, with a rim of relative hyper-enhancement at the superior margin. The longest dimension of the pituitary is approximately 2 cm. (b) Composite of CT images of the left kidney, first visit and one year later- Serial contrast media-enhanced CTs of the abdomen demonstrate an enlarging left renal mass. The initial scan (October 2004) demonstrates a solid enhancing mass (white arrow) measuring approximately 2.6 cm. Follow-up CT approximately one year later shows slight enlargement (3.0 cm) (white arrow).
