Background: Pituitary stalk interruption syndrome (PSIS) is a rare congenital abnormality of pituitary development, typically diagnosed on magnetic resonance imaging (MRI). It is defined by a thin, discontinuous, or absent pituitary stalk, hypoplasia or aplasia of the anterior pituitary, and an ectopic posterior pituitary gland. This case involves a 38-year-old woman with autoimmune polyendocrinopathy who underwent pituitary MRI for routine assessment of her condition, leading to the incidental discovery of pituitary stalk interruption syndrome.
