However, degenerating thyroid adenomas are the most common cause of thyroid cysts specifically, according to Mayo Clinic. A thyroid adenoma is an overgrowth of normal thyroid tissue. A thyroid cyst is a growth within the thyroid gland that is either completely fluid-filled or partially solid and partially fluid-filled, explains Cleveland Clinic.
Often, solid components are mixed with fluid in thyroid cysts. Cysts are usually benign, but they occasionally contain malignant solid components. Chronic inflammation of the thyroid (thyroiditis). Hashimoto's disease, a thyroid disorder, can cause thyroid inflammation resulting in nodular enlargement.
Most thyroid cysts do NOT cause any symptoms at all (2). In fact, they are almost always picked up by routine exam and most patients are surprised to know that they have a nodule or cyst on their thyroid. Some thyroid cysts may cause symptoms if they are too large or if they grow too quickly.
Nobody knows for sure what causes thyroid cysts or thyroid nodules (lumps) in general. Some experts think that people who do not get enough iodine in their diets might be more susceptible to thyroid nodules.
Thyroid nodules can also degenerate and become fluid-filled sacs entirely or have a combination of solid and cystic areas. Thyroid cysts can become large due to sudden bleeding within them. If they rapidly enlarge, they can cause symptoms like difficulty in swallowing, pain, and rarely change in voice due to compression on the vocal cords.
A thyroid cyst is a dilated area of the thyroid which is either exclusively filled with fluid, or contains both fluid and solid parts.…Thyroid Cyst: Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis.
Thyroid cysts represent enlarged fluid-filled regions of the thyroid that may be small (less than 1 cm) or quite large and sometimes arise very suddenly. A cyst, by definition, contains fluid. Thyroid nodules may be entirely cystic, in which case there are no solid components detectable within the fluid.
