Background: Recent evidence suggests that detection of fetal goitre (defined as fetal thyroid circumference >95th percentile) may be a useful way of detecting over and under activity of the fetal thyroid in maternal Graves’ disease. Clinical translation is made difficult by the large differences in normative data from different populations. We examined fetal thyroid circumference in our population against normative data based on at least 150 examinations. Normative da...

Case history: Pre pregnancy: A 31-year-old female with no family history of thyroid disease presented with clinical hyperthyroidism and large goitre with bruit. Graves’ Disease was confirmed: TSH <0.01 (0.35–5.0 mU/l), free T4 53.4 (9.0–21.0 pmol/l), TSH Receptor Antibodies (TRAB) >40 (0–1.9 U/l), TPO 32.2 (<6 U/ml). She started on carbimazole (CBZ: 20 mg BD) and propranolol. She then switched to propylthiouracil (PTU: 150 mg BD) at 2 months due...

Background: Acromegaly is rarely encountered in pregnancy and the lack of data for clinical outcomes limits the development of evidence-based guidelines. We present the case of a pregnancy in a 31-year-old woman with acromegaly due to a pituitary microadenoma.Clinical case: The patient underwent trans-sphenoidal hypophysectomy in 2015 at the age of 28, which was non-curative: post-operative IGF-1 was 533 mcg/l (72–259 mcg/l) (down from 894 mcg/l pre...

Background: Guidelines from ATA and the Endocrine society suggest the use of fetal thyroid monitoring in maternal Graves’ disease to detect fetal thyrotoxicosis or hypothyroidism in response to maternal thyroid receptor antibodies (TRAb) or thionamide therapy respectively. The literature examining how effective this policy is remains sparse, since these remain unusual clinical situations for most centres. Here we review our experience of scanning for fetal goitre.<p c...
