31
Q

What is the interpretation go TSH results? What additional tests should be added?

A

Elevated TSH is consistent with hypothyroidism
- Request thyroid peroxidase Abs (Hashimoto’s)

Suppressed levels are consistent with hyperthyroidism
- Request free T3 and T4

32
Q

What is the first line test for investigating thyroid nodules?

A

Fine needle aspiration

Can be US guided (allows for estimation of nodule size)

33
Q

Mr Fry is a 23-year-old bartender who presents to his GP concerned about a lump in his neck. On further questioning he reveals that he has noticed a very slight swelling in his neck ‘above his Adam’s apple’ for the past few years. However, the lump has approximately doubled in size over the course of the last week. It is not painful and he is aware of no other lumps. He has recently suffered from an upper respiratory tract infection, and had to take one day off work last week, but is otherwise fit and well. He takes no regular medications and has no known allergies. He smokes 10 cigarettes each day, and consumes
about 35 units of alcohol (as spirits) each week.
On examination, there is an upper midline neck lesion measuring 2 cm × 2 cm. When Mr Fry is asked to stick his tongue out or swallow the lump rises up his neck. It does not appear to be attached to the large neck muscles. The lump has well-defined boundaries and a smooth surface. It feels cystic and is nonpulsatile. It is mildly tender to palpation. The overlying skin appears normal. No other lumps are detected on clinical examination.

A

Thyroglossal cyst

34
Q

Mrs Slocock is a 47-year-old housewife who presents to her GP with a lump in her neck. She reports that she has recently noticed a slight swelling in the right side of her neck. She first noticed the lump about 6 weeks ago when she happened to feel her neck (for no particular reason) and noted slight asymmetry.
She has continued to feel the lump every few days but is unsure whether it has changed in size. The
lump is not painful and she is not aware of any other lumps. She reports feeling well, has no significant
past medical history, and takes no regular medicines. She has never smoked, but drinks approximately two bottles of wine per week.
On examination there is a 2 cm × 2 cm lump in the deep tissues of the upper right anterior triangle. The lump does not appear to be attached to sternocleidomastoid. It is firm, non-tender, and has a transmitted pulse. It is possible to move the lump from side to side but not up and down.

A

Carotid body tumour

35
Q

Mr Farquhar is a 22-year-old trainee accountant who presents to his GP with a lump in the left side of
his neck. The lump has been present for a couple of weeks and has gradually been increasing in size.
Mr Farquhar remarks that he has had a slight swelling in the same place on two previous occasions, but
the lump was less prominent and gradually disappeared over the course of a week. On specific questioning,
both of these previous episodes corresponded with an upper respiratory tract infection. The last episode was approximately one month ago. His current lump is not painful. His is aware of no other lumps. He is currently well, takes no regular medications, and has no allergies. He is teetotal, does not smoke, and has never smoked.
On examination, there is a single palpable lesion in the left anterior triangle, anterior to the junction
of the superior third and inferior two-thirds of sternocleidomastoid. The lump does not move when Mr Farquhar is asked to swallow or stick out his tongue. The lump is smooth, non-tender, fluctuant, and non-pulsatile. It measures approximately 2.5 cm × 2 cm and is not mobile.

A

Brachial cyst

36
Q

What are the anatomical borders of the anterior triangle?

A

Inferior ramus of the mandible, the posterior border of sternocleidomastoid and the midline of the anterior neck

37
Q

What are the anatomical borders of the posterior triangle?

A

Posterior border of sternocleidomastoid, the superior border of the clavicle and the anterior border of trapezius

38
Q

A patient presents with intermittent painful swelling of the parotid gland on one side of his face. Which single question will you ask him about precipitants of the swelling?

A

Whether the painful swelling is related to eating

39
Q

What is the Ann Arbor classification for staging lymphoma?

A

i) Lymphoma in a single region, usually one lymph node
ii) Lymphoma in two separate lymph node regions on the same side of the diaphragm
iii) Lymphoma on both sides of the diaphragm +/- the spleen
iv) Disseminated extra nodal disease

40
Q

What is the pathophsiology of Graves’ disease?

A

Autoimmune, non-destructive, stimulatory thyroid disease

The underlying mechanism is antibody-mediated stimulation of the TSH receptor

41
Q

What is the pathophysiology of Hashimoto’s disease?

A

Autoimmune destructive thyroid disease

Antithyroid antibodies are present including antibodies to the TSH R

Underlying mechanism is T-cell mediated destruction of the thyroid gland

Usually presents as hypothyroidism

42
Q

What are the histological types of thyroid neoplasia? What are most common?

A 
Papillary (~60%)
Follicular (~25%)
Medullary (~5%)
Lymphoma (~5%)
Anaplastic
Metastatic
43
Q

What features will raise suspicion of malignancy in patients with a solitary midline neck nodule?

A 
Male
Age 70yrs
Rapid growth
Compression symptoms
Previous neck irradiation
Family history of MEN

Examination
