A 57-yr-old male presented with hyperthyroidism (serum T4, 18 μg/dl) intractable by subtotal thyroidectomy. Workup 1 yr after thyroid surgery showed elevated values of plasma TSH (480 /μU/ml), αTSH (68 ng/ml), T4 (15.9 μg/dl), T3 (23... W Waldhäusl,P Bratuschmarrain,...
At each of these visits patients were clinically evaluated for signs or symptoms of hyperthyroidism./p pResults/p pBiochemical evidence of hyperthyroidism was evident in 77% of patients postoperatively despite of preoperatively normal serum levels. TSH dropped from 1.18 ± 0.06mU/L to 0.15 ± ...
is approx 1–2 per 1000 women and 1 per 10,000 men, with higher rates in older individuals (1). Autoimmune (Hashimoto’s) thyroiditis is the cause of spontaneous primary hypothyroidism in the vast majority of cases. Postablative hypothyroidism after therapy for hyperthyroidism or thyroid surgery...
TSH-secreting pituitary adenoma (TSH-OMA) causing secondary hyperthyroidism was less likely in view of suppressed thyroglobulin levels ruling out an endogenous cause of increased thyroid hormone production, past history (although it may occur at any time), and a low fT4 when measured by different ...
The electrocardiogram demonstrated new-onset AF with no evidence of ischaemia, and preliminary laboratory findings revealed mild leukocytosis, a normal serum electrolyte panel and hyperthyroidism (TSH 0.08mIU/L; fT4 31pmol/L). Serial cardiac enzymes levels were not raised, and an urgent chest X-ray...
Thyroid function testsrevealedhyperthyroidismwith TSH concentrations <0.000 μIU/mL, free T3 levels of 12.84 pg/mL, and free T4 levels of 2.84 ng/mL. No abnormalities inblood glucoseand electrolyte levels were detected. A braincomputed tomographyscan showed no meaningful abnormalities. Color-codedultra...
Thyrotropin-secreting pituitary adenomas (TSHomas) Thyrotropin are a rare cause of secondary hyperthyroidism and account for less than 2% of all pituitary adenomas. In the last 30 years, the recognition of TSHomas has been facilitated by the...
SUMMARYA young women presenting with hyperthyroidism proved to have diffuse infiltration of the thyroid with carcinoma probably from a primary breast adenocarcinoma. The gland was diffusely infiltrated with tumour although the thyroid follicles were intact. Blood thyroid hormone levels were raised but ...

Postablative hypothyroidism after therapy for hyperthyroidism or thyroid surgery is the second most common cause. Drugs may also precipitate primary hypothyroidism, especially in people with underlying autoimmune thyroid disease (i.e., positive antithyroid antibodies). Lithium and iodine-containing drugs ...
