摘要
为了研究甲状腺腺瘤声像图改变的病理学基础，对８６例患者进行了术前超声和术后病理检查。发现肿瘤细胞和滤泡的大小及排列方式，以及血管和纤维组织的含量及分布状态决定了腺瘤的回声强度，而腺瘤的出血和囊性变常导致声像图上腺瘤多以混合性肿块出现。包膜外的微血管、甲状腺组织受压萎缩。
In order to study the pathologic basis of the ultrasonographic changes in thyroid adenomas, preoperative ultrasonography and postoperative pathologic examinations were performed on 86 patients with thyroid adenomas. It was found that echo intensity was determined by the size and arrangement pattern of the tumor cells and follicles together with the distribution and amount of the blood vessels and fibrous tissue in adenoma. Hemorrhage and cystic degeneration of adenoma frequently caused the thyroid adenoma appeared as a mixed mass on ultrasonography. The dark ring was chiefly produced by the microvessels outside the capsule, the compression and atrophy of the adjacent thyroid tissue, the inflammatory exudation and the capsule itself.
