高频彩超对甲状腺腺瘤及结节性甲状腺肿的诊断价值

目的探讨高频彩超对甲状腺腺瘤及结节性甲状腺肿的诊断价值。方法应用高频彩超对68例甲状腺腺瘤和104例结节性甲状腺肿进行检查,观察结节的部位、数目、形态、边缘、内部回声及CDFI血流信号特征。结果甲状腺腺瘤和结节性甲状腺肿结节的结节数目、边界是否有包膜、结节内部及周边血流信号等方面差异均有显著性（P均〈0．05）。结论高频彩超对甲状腺腺瘤及结节性甲状腺肿的诊断具有较大意义。     

Grayscale and Color Doppler Features of Testicular Lymphoma

Pooled data from 16 radiology centers were retrospectively analyzed to seek patients with pathologically proven testicular lymphoma and grayscale and color Doppler images available for review. Forty‐three cases were found: 36 (84%) primary and 7 (16%) secondary testicular lymphoma. With unilateral primary lymphoma, involvement was unifocal (n = 10), multifocal (n = 11), or diffuse (n = 11). Synchronous bilateral involvement occurred in 6 patients. Color Doppler sonography showed normal testicular vessels within the tumor in 31 of 43 lymphomas (72%). Testicular lymphoma infiltrates through the tubules, preserving the normal vascular architecture of the testis. Depiction of normal testicular vessels crossing the lesion is a useful adjunctive diagnostic criterion.     

甲状腺腺瘤与单发结节性甲状腺肿的超声鉴别诊断

目的探讨超声检查在甲状腺腺瘤和单发结节性甲状腺肿诊断和鉴别诊断中的价值。方法对经手术和病理证实的24例甲状腺腺瘤和16例单发结节性甲状腺肿的二维及彩色多普勒声像图进行比较分析。结果上述二组疾病在甲状腺的大小、回声，结节的大小、回声，结节的周边低回声晕以及结节内部和周边血流信号方面声像图具有特征性改变。结论甲状腺腺瘤和结节性甲状腺肿两者的不同病理基础构成了各自超声声像图特征，有助于对二者的诊断及鉴别诊断。     

Amyloid Goiter: A Diagnosis to Consider in Diffuse Fatty Infiltration of the Thyroid

An amyloid goiter is the presence of amyloid protein in the thyroid in sufficient amounts to produce enlargement of the gland, accompanied by fat deposition of varying extents. It can be seen in long‐standing inflammatory disorders such as familial Mediterranean fever. Imaging findings depend on the amount of fat and amyloid deposition; however, the main imaging finding is diffuse fatty infiltration of the thyroid. Herein, the multimodality imaging features in 3 cases of amyloid goiters secondary to familial Mediterranean fever are presented.     

Primary Malignant Fibrous Histiocytoma of the Thyroid: Two Case Reports and Review of the Literature

Primary malignant fibrous histiocytoma of the thyroid is an uncommon malignancy of the thyroid. Because it is rare, fewer than 20 cases have been reported in the literature, and the sonographic features of only 2 cases have been reported between the 1980s and 2014. Here we report 2 cases of primary malignant fibrous histiocytoma of the thyroid with an emphasis on the sonographic findings, and we review the published literature.     

Surveillance Neck Sonography After Thyroidectomy for Papillary Thyroid Carcinoma: Pitfalls in the Diagnosis of Locally Recurrent and Metastatic Disease

A sonographic examination of the neck performed 6 to 12 months after thyroid surgery in patients with differentiated thyroid cancer is strongly recommended by the American Thyroid Association and considered mandatory by the European Thyroid Association for locoregional surveillance. The aim of this article is to review the normal anatomic changes expected after thyroid surgery and the pathologic mimics of thyroid carcinoma recurrence in post‐thyroidectomy patients as they appear on neck sonography. We hope to offer some pearls to increase diagnostic confidence in this setting.
