What Can Cause a Thyroid Lesion?

Diffuse thyroid disease is a disease of the thyroid gland. The most common clinical types of diffuse thyroid disease are nodular goiter (hereinafter referred to as nodule), thyroid cancer (hereinafter referred to as nail cancer), and Hashimoto's thyroiditis (below). (Called Hashimoto's disease), Graves' disease, etc. Due to the different treatment schemes for each disease, it is necessary to make a qualitative diagnosis of such diseases before treatment.

Diffuse thyroid disease

Diffuse thyroid disease is a disease of the thyroid gland, and the most common clinical types of diffuse thyroid disease are

Objective To analyze the CT imaging manifestations of diffuse thyroid lesions in order to obtain the main points of CT differential diagnosis of various diffuse thyroid lesions. Materials and methods Retrospective analysis of CT data of 50 cases of diffuse thyroid disease

Analysis of common diseases of diffuse thyroid lesions

In another group of cases, the author divided the thyroid lesions into three types according to their CT manifestations, namely limited nodular type, diffuse large and diffuse mixed nodules (referred to as mixed type) [1], according to In this classification, the 50 cases in this group belong to the latter 2 types. According to multiple groups of data at home and abroad [1 to 6] and the author's work experience, the four cases collected in this group are the most common types of diffuse thyroid lesions, so it is necessary to compare and analyze their CT images to find out The CT characteristics of each disease can reach the purpose of diagnosis and differential diagnosis of each disease.

Analysis of CT signs of 4 kinds of diffuse thyroid lesions

Comparative analysis of the CT image data of the four lesions in this group found that the CT manifestations of the same disease cases have many common features; and different CT characteristics also exist among different disease species. In the following, based on the literature and the data in this group, the main points of CT diagnosis and differential diagnosis of 4 different lesions are analyzed and discussed.

(I) General Nursing

1, appropriate rest and activities.

When clinical symptoms are significant, bed rest should be timely, especially when the activity is restricted from 1 to 2 hours after eating. When clinical symptoms are significantly improved, pay attention to rest while taking appropriate activities or physical exercise. Avoid overwork; All laboratory tests are normal and may not restrict activities.

Hyperthyroidism

Main symptoms: The acute phase of the eye process is manifested by the inflammatory response of extraocular muscles and tissues behind the eyeball. Extraocular muscles can be significantly thickened, increasing by 3 to 8 times compared to normal, and the fat and connective tissue infiltration, infiltration, and volume can increase up to four times after the ball. Chronic changes are mainly proliferative. There are similar pathological changes in the lacrimal gland. Conscious symptoms include foreign body sensation in the eye,

Subclinical hyperthyroidism refers to hyperthyroidism with normal FT4 and FT3 levels and lower TSH. The cause can be divided into temporary and persistent. Temporary mainly include: subacute thyroiditis, Hashimoto's thyroiditis, postpartum thyroiditis, drug-induced thyroiditis and so on. The main ones are: Graves disease, autonomic functional thyroid tumor, etc. Subclinical hyperthyroidism can be asymptomatic and most do not require treatment, but those with a high thyroid autoantibody titer tend to progress to clinical hyperthyroidism or clinical hypothyroidism, and further treatment is needed.

Subclinical hyperthyroidism can be divided into two types: exogenous and endogenous. The former mainly refers to drugs (including superphysiological doses of thyroid hormones). In addition, i. Inflammation can also manifest as subclinical hyperthyroidism. The latter refers to thyroid disease (including Graves' disease, multinodular goiter, and autonomic thyroid adenoma). The risk of osteoporosis in subclinical hyperthyroidism may be increased, and the risk of atrial fibrillation may be increased, and subclinical hyperthyroidism is one of the risk factors for atrial fibrillation. Aure et al. Studied 23 628 subjects and found that the incidence of atrial fibrillation was 13.3% in patients with serum TSH concentration less than 0.14 milliunits per liter (Mu / L), which was significantly different from those with normal serum TSH concentration. The risk was 5.2%. It is recommended to give appropriate treatment.
