甲状腺位于颈前,是身体的主要内分泌器官。近年来影像检查普遍开展,许多人在体检中被查出有甲状腺占位性病变。占位性病变是影像学发现有病灶,但暂时不能明确诊断的描述,包括肿瘤、肿块等。病例分析发现,主要有以下几种类型。结节性甲状腺肿以中年女性多见。在机体甲状腺激素相对不足时,垂体分泌促甲状腺素(TSH)增多。由于TSH的长期刺激,反复或持续增生导致甲状腺不均匀增大和结节样变。结节内可有出血、囊变和钙化,大小不一,有的可在颈前摸到中等硬度 The thyroid gland is located in front of the neck and is the body’s major endocrine organ. In recent years, imaging tests are generally carried out, many people were found in the physical examination of thyroid lesions. Space-occupying lesions are found lesions of the imaging, but temporarily can not confirm the description of the diagnosis, including tumors, lumps and so on. Case analysis found that there are mainly the following types. Nodular goiter more common in middle-aged women. In the body when the relative lack of thyroid hormone, pituitary secretion of thyroid-stimulating hormone (TSH) increased. Due to long-term stimulation of TSH, repeated or persistent hyperplasia leads to non-uniform thyroid gland enlargement and nodular degeneration. Nodules may have bleeding, cystic and calcification, the size of different, and some can feel in the neck before the moderate hardness
