Thyroid cyst containing liquid bladders found in the thyroid, thyroid cysts are usually no symptoms, unless the cyst is large or there is bleeding within the cyst phenomenon, this time may cause some compression symptoms such as pain, difficulty swallowing, difficulty breathing, hoarseness. In general, thyroid cysts rarely malignant cells, usually only observe, to see if there are larger trends can be.
basic overviewthyroid cysts tumor was round, diameter between 2 and 5 cm. Smooth, and generally hurt or slight pain, move up and down with swallowing. Most of the single nodule, rare multiple nodules. thyroid intracapsular pressure is not high, the texture is more soft, if the liquid is more, the texture will be more resilient.
thyroid cyst schematic
patients with no apparent feeling, usually inadvertently found that the anterior Ministry of tumor. Usually check ultrasound diagnosis is cystic or nodular, the distinction between the thin-walled or thick-walled cyst. The cysts were benign, thyroid cancer with cyst are rare.
ultrasound can be seen within the mass of liquid dark area, and the substantive nodules difference. radionuclide imaging is more than "cold nodule". thyroid function tests within normal limits. thyroid cysts are mostly benign. With cyst of thyroid cancer is rare, about 1% -2% of the cancerous cysts cyst fluid cytology is usually able to find cancer cells. The absorb the iodine thyroid hormone concentration in the blood consequent reduced nerve - humoral regulation of the pathway, the anterior pituitary secretion of large amounts of thyroid-stimulating hormone, to promote thyroid swelling, this swelling is actually compensatory enlargement of the thyroid is a shortage of thyroid function.
early expansion of the follicle is more evenly scattered in the glands of the ministries, the formation of a diffuse goiter. If not treated, the lesions continue to develop the expansion of the follicular gathered into several nodules of varying sizes, the gradual formation of nodular goiter (nodular goiter). Some nodules can occur due to poor blood supply, degeneration caused by cyst formation.
symptomssymptoms of thyroid cysts mainly heart palpitations, chest tightness, heat intolerance, sweating, tremor, insomnia, appetite, hyperactivity, weight loss, fatigue, diarrhea, goiter and eye prominent and more acute onset of signs and symptoms of thyroid unilateral or bilateral swelling and hard, accompanied by local pain, and often to the ears, behind the top of radiation, the body may have chills, fever, more common in middle-aged women . thyroid morphology was mostly diffuse increase; some can be nodular, no pain, no systemic symptoms of thyroid cyst symptoms; individual symptoms of hyperthyroidism, the disease for a long time who may have some kind of thyroid function to reduce the symptoms, such as reducing appetite weakness, mild edema.
within the leaf of the thyroid mass, slow growth, usually single, intact membrane, clear boundaries with the surrounding normal tissue, pain and tenderness, nodular texture, medium hard, smooth surface, adhesion with the surrounding, you can move down with swallowing. Neck enlargement (goiter due), the texture is generally softer, significantly swollen cervical tumor may be protrusion of falling backward or oppressed cause shortness of breath or difficulty breathing, or caused by swallowing resistance choking feeling; from time to both the size of the nodules of nodular and hard and soft, and some nodules hard; usually no systemic symptoms. No obvious symptoms of thyroid cyst early, only the cervical area appear hard painless mass, surface uneven and rapid tumor growth rate, the upper and lower mobility when swallowing. Then, cervical lymph node metastasis; can compression symptoms such as shortness of breath, swallowing resistance choking, hoarseness, and horner syndrome (disease side miosis, upper eyelid ptosis, enophthalmos, and sweat-free face with side head) . Occurs in puberty, pregnancy or lactation, thyroid mild or moderate swelling, a smooth surface, soft texture, normal thyroid function tests, often self-healing, hyperthyroidism, hypothyroidism should be discharged and other reasons caused by goiter possibility. Most of the single nodule, occasionally multiple nodules, the diameter of 2-5 cm. The lesions were round, smooth surface, clear boundary, the majority of pain or mild pain, no tenderness, with swallowing move up and down thyroid function to check in the normal range. With cyst of thyroid cancer is rare, about 1% -2% of the cancerous cysts cyst fluid cytology is usually able to find cancer cells.
It is understood that nodular goiter in thyroid cyst about 5% ~ 20%. thyroid nodules or adenomas oppression around the vein, resulting in local blood circulation disorders, ischemia, degeneration and necrosis, interstitial congestion and edema, fluid accumulation in the formation of cysts. If the blood vessels rupture, the formation of the cyst with hemorrhage. Depending on the nature of the cyst contents can be divided into a colloid cyst, serous cysts, hemorrhagic cysts, necrosis, cyst and mixed cysts. collagen capsule is merging made by the thyroid follicular sac of fluid viscosity, light tribute color, non-iodized thyroglobulin; serous cyst more than degradation from thyroid nodules or adenomas, cyst fluid thin colorless; hemorrhagic cyst cyst fluid for the old blood was brown; and necrosis and mixed swollen cyst fluid of necrotic tissue and old blood. Simple thyroid cysts are rare, more common nodular goiter part in the clinical merger of cystic change. This is a goiter, part of the organization of vascular hemorrhage or absorption, the formation of multiple small cysts, the integration of multiple cysts form large cyst.
cyst characteristicsperformance of thyroid cyst is smooth, the pressure of a tension, B ultrasonic anechoic fluid level, puncture to see that the liquid is a clear diagnosis. thyroid cyst, benign, with rare cyst of thyroid cancer, about 1% to 2%. Found that B thyroid cyst wall papillae, to be alert to the possibility of thyroid carcinoma with hemorrhage and cystic degeneration. hardener can make the wall of aseptic necrosis occurs, the wall adhesions, fibrosis, cyst occlusion, for therapeutic purposes, the success rate of 90% or more. thyroid cyst mass was circular, the diameter in the range of 2 to 5 cm. Smooth, and generally hurt or slight pain, move up and down with swallowing. Most of the single nodule, rare multiple nodules. thyroid intracapsular pressure is not high, the texture is more soft, if the liquid is more, the texture will be more resilient.
