MRI showed an enhancing pituitary mass measuring 1.2 cm maximum height, extending suprasellarly and distorting the optic chiasm. Visual field testing showed bilateral constriction. 0900 h cortisol was 502 nmol/l, thought to be relatively low for the stage of pregnancy and FT4 was 9.3 pmol/l suggesting TSH deficiency. Prolactin was appropriately raised for the gestational age at 4951 mU/l.<...

A 51-year-old asymptomatic man presented in 1998 with elevated thyroid stimulating hormone (TSH) 6.34 mIU/l (0.34–5.6 mIU/l), FT4 54.1 pmol/l (7.5–21.1 pmol/l), FT3 20.1 pmol/l (3.0–5.0 pmol/l) and TSH-α subunits 3.6 mcg/l (<2.0 mcg/l). After the first visit, he was lost to follow-up.He presented 10 years later in 2008 with 1-week history of symptoms of heart failure and hyperthyroidism. Clinically he was thy...

An 82-year-old man presented with weight loss and lethargy. Thyroid function tests showed a fT4 7.6 pmol/l and TSH 0.08 mU/l. Short synacthen test confirmed hypoadrenalism with baseline cortisol of 34 nmol/l and 30 min sample 156 nmol/l. He had low gonadotrphin levels and Prolactin was 551 μ/l. He was commenced on hydrocortisone and levothyroxine treatment with symptomatic improvement. An urgent CT scan revealed multiple enlarged lymph nodes above and below the diaphragm ...
