Objective To discuss the diagnostic and differential diagnostic value of ultrasonography for primary testicular lymphoma (PTL) by studying the ultrasonographical image characteristics. Methods Thirty-one patients with PTL confirmed by postoperative histopathology between 2005 and 2015 were chosen to be the study subjects. We retrospectively analyzed their ultrasonographical features and clinical data. Results Most PTL patients were elderly men, and the initial symptom was mainly painless testis enlargement. Thirty-nine testicles were involved in the primary testicular lymphoma, including 23 unilateral and 8 bilateral. In the 31 patients, 22 had diffuse lesions and 9 nodal. Ultrasonography showed that most tumors were hypoechoic lesions, and part of them were hyperechoic linearly. The lesions had abundant blood flow signals with a low resistance index. Conclusions In elderly patients with painless testicular enlargement, the possibility of primary testicular lymphoma must be fist considered. Manifestations of primary testicular lymphoma have some distinctive characteristics, and combined with clinical history, they are helpful for the diagnosis and differential diagnosis of PTL.
目的 通過總結韌帶樣型纖維瘤病（DF）的超聲圖像表現和病理學結構，以提高對DF的認識和診斷水平。 方法 回顧性分析2005年1月－2011年12月70例經手術和病理組織學證實為DF患者的超聲圖像和病理組織學結果。 結果 DF腫塊的超聲表現與病理結構密切相關。70例DF中腹部外型41例（58.6%）、腹壁型18例（25.7%）、腹內型11例（15.7%）。DF的典型超聲圖像表現為沿肌纖維浸潤性生長的低回聲腫塊,累及多塊肌肉；腫塊無包膜,多數形態不規則、邊界不清；其中8例包繞和侵犯相鄰骨質, 12例腫瘤壓迫或侵犯鄰近血管、神經、腸管等組織；40例瘤體內探及Ⅰ級血流信號，4例探及Ⅲ級血流信號；所有病變均未見壞死出血和囊變，病變周圍無淋巴結腫大。 結論 DF的聲像圖表現有較強的特征性，超聲能較為準確判斷腫塊累及范圍、是否侵犯相鄰骨質、與毗鄰血管、神經的關系，有助于制定手術計劃。
