Thyroid cyst: treatment, symptoms,the reasons

Update: October 2018

A thyroid cyst is a disease characterized by
the appearance in the body tissue of benign tumor
formations filled with homogeneous colloidal content
(colloid cyst of the thyroid gland) and dense formations
(complex or complicated cysts).

These states are also called thyroid nodes and cysts.
glands. Their difference is that the cyst has a cavity,
filled with fluid, while the nodes are actually composed of
altered glandular cells. The sizes of cysts are often small (less than 1
cm), but can increase significantly, and this can happen
swiftly.

components of the cyst. In the structure of the incidence of the population frequency
cyst development is 1-5% of the total number of patients with
нарушениями функций glands.

Withчины возникновения кисты

Simple cysts can be the result of exposure to a multitude of
factors from viral infection to simple blockage of the duct gland
in view of the individual anatomical features of the structure of the organ.
With развитии инфекционного заболевания, сопровождающегося
gland inflammation, a cyst can develop as a secondary
symptom.

Complex cysts contain fluid and dense particles and have similar
symptoms with colloidal formations. To risk factors and causes
cysts on the thyroid gland include:

  • Cancer, radiation and chemotherapy
  • A cyst may form as a result of hemorrhage.
  • Malnutrition (dystrophy) of the gland
  • As a result of the increase in her follicles
  • With недостаточном поступлении йода с пищей
  • Autoimmune diseases accompanied by inflammatory
    gland changes (goiter Hashimoto)
  • Radiation exposure in childhood
  • Female
  • Age over 40 years
  • The presence of a thyroid cyst in parents, brothers or
    sisters.
  • Cystic formations in the thyroid gland in women are found
    4 times more often than men.
  • Residents of regions with
    insufficient amount of iodine in food and water.
  • In patients undergoing exposure to ionizing radiation in
    for 1 calendar year, the thyroid cyst develops in
    2% of cases.

Symptoms of thyroid cyst

Patients with cysts of small size (up to 3 mm) do not mark
no manifestations of the disease and feel completely healthy
by people. Most of them learn about the disease only after
identify them by a physician upon examination. As the size increases
The symptoms of a thyroid cyst become more pronounced.
The first manifestation of a progressive cyst is a “lump” in the throat.
Also for the first time, a cyst can be suspected by the appearance of an enlarged
education on the neck, which is easily felt through the skin. TO
Other common symptoms include: TOиста щитовидной железы: лечение

  • Difficulty breathing (due to compression of the trachea with a cyst);
  • Pain in the gland area, may spread to the lower jaw
    and ear;
  • Pain when swallowing or inability to swallow food;
  • The change in timbre (rarely observed, due to
    compression of an enlarged cyst specific nerve fibers).

There are several stages in the development of the disease:

  • Stage of cyst formation. Asymptomatic. Disease
    at this stage is detected by chance during prophylactic
    inspection;
  • Stage of growth. With скоплении большого объема жидкости в полости
    cysts its size gradually increases, which leads to the development
    characteristic symptoms. The doctor may suspect the presence of the disease
    already at visual examination. The diagnosis is easily confirmed by
    laboratory tests;
  • Stage of resorption. With удовлетворительном состоянии иммунной
    system disease passes on its own, and the cyst is exposed
    scarring, without causing severe disturbances of the state of the body.

With злокачественном течении заболевания кисты могут
перерождаться в раковую tumor. Such formations have a dense
consistency and distinguished by rapid uncontrolled growth. Also
it is noticed that the malignant course of the disease is more often
accompanied by a change in voice due to the rapid growth of the cyst.

A common concomitant symptom of the disease is
dysfunction of the thyroid gland, characterized by
or decreased hormone production. Due to dysfunction

With осложненном течении кисты в области измененной ткани
edema and development of bacterial flora appears, which leads to
inflammatory changes and accumulation of pus. Symptoms
adhering infections are increasing acute pain
in the neck, swelling, fever. Characteristic symptom
is an increase in cervical lymph nodes.

Diagnostics

Main method Diagnostics – this is visualization using ultrasound. WITH
using ultrasound, determine the size,
the structure of the cyst and surrounding healthy tissue. This method
allows not only to diagnose a cyst with high accuracy, but also
conduct differential diagnosis with adenoma, nodular goiter and
other diseases.

Биопсия кисты held для определения типа кисты и исключения
злокачественного process. With взятии биопсии используется
тонкая игла, которая held в кисту под контролем УЗИ.
The procedure is not particularly difficult and is carried out under
local anesthesia. For more accurate diagnosis, taking material
It is produced from several cyst departments or from various cysts. By
the nature of the cyst content obtained during a biopsy is judged on its
type:

  • Yellow, purple, or dark brown color of fluid in the cyst.

  • The presence of pus in the cyst indicates adherence

cases.

re-study.

Puncture of a cyst may be accompanied by its complete emptying with
the subsequent introduction into the cavity of sclerosing substances. The

As additional methods are used:

  • Angiography for the prevention of vascular complications;
  • Laryngoscopy with hoarseness and other changes

  • Bronchoscopy to assess the condition of the trachea during cyst growth

  • TOонтроль уровня гормонов щитовидной glands.

Can I delete a cyst?

And although in most cases, thyroid cysts
benign, but their “behavior” is unpredictable:

  • In some cases, they do not give negative dynamics for years.
  • In others, they are growing rapidly.
  • Thirdly – they pass by themselves.
  • Usually the reason for going to the doctor is the growth of a cyst to the size
    (over 3 cm), visible to the eye, and causing deformation of the neck,
    hoarseness or loss of it, lump in throat, breathing disorder
    and functions of swallowing, neck pain.

If a cyst is less than 1 cm in diameter, it is only observed, with
its increase is carried out with a puncture followed by cytological
research. If after emptying the cyst in it again
content is accumulated, the question of its removal is solved. None
warming compresses or lotions on cysts put in no way

Surgical treatment for malignant disease is usually

the presence of a clear indication of the operation is recommended in

Forecast

Cysts that have a benign course have a positive
prognosis and with the right treatment pass without consequences for
the patient. In many cases, patients do not even need to undergo
treatment. Enough testing in dynamics.

Heavier course and prognosis for the life of the patient has
malignant course in which a cyst is reborn into a cancerous
tumor. The risk of malignancy also increases if
a thyroid cyst is diagnosed in a child (14–40% of cases,
compared to 5% in adults).

The percentage of treatment efficacy in patients with malignant
course of the disease is about 80% in the early stages and
significantly reduced with the development of metastases and tumor germination
to nearby organs.
