The Pickardt-syndrome (or Pickardt-Fahlbusch-Syndrome) is a rare form of tertiary hypothyroidism that is caused by interruption of the portal veins connecting hypothalamus and pituitary, e.g. due to tumors compressing the infundibulum.

Other endocrine disorders that may be associated with Pickardt syndrome are suprasellar failures like secondary hypogonadism and functional hyperprolactinemia.
