Ultrasonographic examination was carried out in 90 patients in whom single thyroid nodule was found by palpation and scintigraphic examination. In 67 of these patients (61%) the presence of a single nodule was confirmed by ultrasonography. In the remaining 23 (38%) multiple nodules were found within the gland. Ultrasonographic examination made possible the differentiation of solid lesions from the cystoid ones in 100%. Follicular adenomas appeared in ultrasonography as mixed-type nodules with the features of degeneration characterized by the presence of the areola (the so called "halo"). The Hurtle's adenomas appeared as mixed-type nodules, hypo-echogenic and devoid of areola. The observed neoplastic lesion (carcinoma follicular) was of a cystoid type. The appearance of cystoid lesions made possible the differentiation of simple cysts from those originating from tumor decomposition. Ultrasonography may then be helpful not only for distinguishing between cystoid-type and solid type lesions but also for classifying solid nodular structures as malignant or benign.
对90例经触诊和闪烁扫描检查发现有单个甲状腺结节的患者进行了超声检查。其中67例（61%）患者经超声检查证实存在单个结节。其余23例（38%）在腺体内发现多个结节。超声检查能够100%区分实性病变和囊样病变。滤泡性腺瘤在超声检查中表现为具有退化特征的混合型结节，其特征为存在晕圈（所谓的“晕”）。许特耳腺瘤表现为混合型结节，低回声且无晕圈。观察到的肿瘤性病变（滤泡癌）为囊样型。囊样病变的出现有助于区分单纯囊肿和肿瘤分解形成的囊肿。因此，超声检查不仅有助于区分囊样型和实性型病变，还有助于将实性结节结构分类为恶性或良性。
