Pituitary stalk interruption syndrome(PSIS) is a rare disease characterized by different degrees of anterior pituitary hormone deficiency.The typical imaging finding is a thin or absent pituitary stalk,often associated with an ectopic posterior pituitary and a hypoplastic anterior pituitary.The cause is still unkown.Dynamic contrastenhanced MRI helps to confirm the diagnosis.Replacement of multiple anterior pituitary hormones is the key of the treatment.Doctors should have a thorough understanding of the disease and give patients efficacious treatment and a better prognosis would be obtained.
