CAT scan of thyroid tumor
So this is not necessarily her. But this is an example of a very large thyroid tumor. And what we can see is, well, how would the trachea appear? Well, so this is the mid-line right here. And this is the trachea. So we see the trachea has been pushed off to one side. And the esophagus is probably sitting right here, probably being crushed by that tumor.

So she's having difficulty breathing, because her trachea is been pushed terribly to one side. It's difficult for her to swallow, because there is a mass in the way. And her hoarseness could be attributed to either trouble with breathing or damage or compression on her recurrent laryngeal nerve.

So although this image is a more complicated one, her course would be typical of a person having a benign thyroid tumor that would be removed.

OK. We will discuss now the diagnosis and physical symptoms associated with a thyroid tumor. So we want to explain why a thyroid tumor might cause difficulties in both breathing and swallowing and how a tumor in one lobe of the thyroid might alter the appearance of a plain film of the neck.

This is a case of a woman. She has a 12-month history of an enlarging neck mass with increasing dysphagia. Dysphagia means difficulty in swallowing. And globus, which is a sense of a lump in her throat. And she's also developed worsening hoarseness.

And she's concerned that she's having trouble breathing, which she attributes the size of the mass. And she says the mass is not tender, but she feels a lump point she swallows.

She has no history of some indicators, no radiation exposure to the neck. And she denies any weight loss or weight gain. That's interesting to us. It makes us think now, if it's a thyroid problem, that the tumor is not causing a variation in thyroid hormone creation.

She doesn't feel unusually hot or cold, which goes along with some kinds of thyroid problems, or any depression nor are increased energy. So she's not depressed or she's not hyperactive, which would be indication of either hypo or hypothyroid condition.

And if you look her thyroid hormone levels, that sort of confirms that. She's got reasonably decent TSH levels and only slightly elevated T3 and T4 levels. She's got normal calcium. We like that, because the thyroid is very intimately involved in blood calcium circulating levels. And otherwise, her lab values are unremarkable, as they say.
