A pseudo-cystic appearance and posterior enhancement are previously reported to be diagnostic sonographic features of lymph node involvement in non-Hodgkin's lymphoma. This study was undertaken to determine whether these ultrasonic features remain with the use of high-resolution transducers.
A review of ultrasound examinations in 32 patients with proven lymphomatous cervical lymphadenopathy (27 non-Hodgkin's lymphoma, five Hodgkin's disease) was performed. A total of 95 lymph nodes were assessed for size, shape, posterior enhancement and internal architecture. All examinations were performed with the same high-resolution transducer and by the same sonologist.
Lymphomatous nodes (irrespective of type) are frequently heterogeneous (68-86%), have a micronodular pattern (63-69%) and less commonly demonstrate posterior enhancement (9-26%).
Using a high-resolution ultrasonic transducer, cervical nodes involved with lymphoma (irrespective of type) commonly demonstrate a heterogeneous micronodular pattern. The pseudocystic appearance of nodes with posterior enhancement in non-Hodgkin's nodes is seen infrequently.
既往报道过假性囊肿样表现及后方增强是超声诊断非霍奇金淋巴瘤淋巴结受累的特征。本研究旨在确定使用高分辨率换能器时这些超声特征是否依然存在。
对32例经证实的颈部淋巴瘤性淋巴结病患者（27例非霍奇金淋巴瘤，5例霍奇金病）的超声检查进行回顾。共评估了95个淋巴结的大小、形态、后方增强及内部结构。所有检查均使用同一高分辨率换能器并由同一位超声科医生进行。
淋巴瘤性淋巴结（无论类型）常为不均匀性（68 - 86%），呈微结节状（63 - 69%），较少表现为后方增强（9 - 26%）。
使用高分辨率超声换能器时，淋巴瘤累及的颈部淋巴结（无论类型）常表现为不均匀性微结节状。非霍奇金淋巴瘤淋巴结出现假性囊肿样表现及后方增强的情况较少见。
