Wilson’s disease (WD) is a rare disorder of copper metabolism usually presenting with variable liver damage and neuropsychiatric symptoms. Here we report a 39-year-old Taiwanese female with late manifestation of WD presenting with gonadotroph, thyreotroph and corticotroph hypopituitarism. Molecular genetic testing revealed compound heterozygosity for two mutations in exons 12 and 14 (c.2828G>A and c.3140A>T). Copper-chelating therapy with D-penicillamine and zinc was initiated along with supplementation of hydrocortisone and L-thyroxine. Hypopituitarism resolved when urinary copper excretion returned to normal levels under copper chelation. This case should raise awareness of pituitary function in WD patients.
Hypopituitarism can complicate Wilson’s disease (WD) and endocrinologists should be aware of it when caring for hypopituitary patients.
Hepatologists should consider endocrinologic testing for hypopituitarism when WD patients present with symptoms of adrenal insufficiency, thyroid or gonadal dysfunction.
Copper-chelating treatment is mandatory and may lead to the recovery of pituitary function in such patients.
