Synonyms: Pickardt-Fahlbusch Syndrome, Pickardt's Syndrome
Pickardt Syndrome is a rare form of tertiary Hypothyroidism that is caused by interruption of portal vessels connecting hypothalamus and pituitary. This typically origines in tumor or thrombosis. In the consequence, an inadequately low amount of TRH reaches the anterior pituitary lobe and hence release of TSH is very low, leading to understimulation of the thyroid with hypothyroidism, in spite of functional thyrotropic feedback control.
