Thyroid Biopsy Results

One of the doctors called this morning with the news.  The nodules are follicular neoplasms. Yes, I didn’t know what those are either, so Sheila did some research and sent me the following:

Follicular neoplasms are thyroid nodules that may be benign or may be a form of thyroid cancer. This situation occurs when samples from a fine needle aspiration biopsy of a nodule reveal clusters of increased numbers of epithelial cells grouped together in specific patterns with small amounts of colloid present. This configuration marks a nodule as a particular kind of growth that is referred to as a follicular neoplasm.

If the cells that have grown to form this nodule remain contained within a thin capsule of tissue that surrounds it, it is a benign thyroid nodule called a follicular adenoma. Alternatively, if the cells grow to penetrate the capsule of tissue to invade normal thyroid tissue or blood vessels within the thyroid gland, it is malignant, representing a form of thyroid cancer called follicular thyroid cancer.

It is not possible to distinguish a follicular adenoma from follicular thyroid cancer on the basis of a fine needle aspiration biopsy sample. To make a definitive diagnosis, it is necessary to surgically remove the nodule so that it can be cut into sections and examined under a microscope to look for any evidence of invasion of normal thyroid tissue or blood vessels.

So there’ll be more conversation to determine if Sheila wants to have a surgical biopsy procedure or not to definitively determine what she has.

In the meantime, her brain MRI is scheduled for the 22nd.
