Clinical question: Evaluate pituitary tumor. Signs and symptoms: History of transsphenoidal resection of pituitary tumor. Pre and post enhanced pituitary MRI:Examination demonstrates postoperative changes of a prior transsphenoidal hypophysectomy. There is a tiny focus of enhancement along the floor of the expanded sella sella in the midline measuring approximately 4 x 1.3 mm in size which could represent scar tissue or remaining pituitary gland. A decreased caliber to the extent with mild enhancement terminates to this focus of enhancement. There is no detectable mass. Enlarged sella likely secondary to priorSignal expansile mass. No detectable abnormality of the suprasellar visual complex and unremarkable cavernous sinuses bilaterally. All visualized paranasal sinuses are well pneumatized.
