[Abstract] Objective: To analyze MRI features of pituitary stalk interruption syndrome to improve diagnostic level.Materials and Methods: The clinical and MRI features of 15 patients with pituitary stalk interruption syndrome proved by MRI were retrospectively analyzed.Results: In all 15 cases, it happened growth hormone deficiency, 2 cases for a single growth hormone deficiency,the rest 13 cases combined with multiple hormone deficiency. With MRI examination,the pituitary stalk was not shown in all 15 cases and ectopic posterior lobe located in infundibulum in all 15 cases,decreased anterior lobe with normal signal in 13 cases, normal height and signal anterior lobe in 2 cases.Conclusion: MRI findings of pituitary stalk interruption syndrome were characteristic, MRI was the best imaging modality for the diagnosis of pituitary stalk interrup tion syndrome.
