Abstract

PURPOSE

To evaluate the relationship between our proposed sonographic classification of testicular tumors by tissue harmonic imaging and histological type.

METHODS

We retrospectively analyzed 58 testicular tumors and tumor-like lesions [seminomatous germ cell tumor (SGCT): 28; non-seminomatous germ cell tumor (NSGCT): 16; lymphoid and hematopoietic tumor (LHT): 7; Leydig cell tumor: 1; epidermal cyst: 2; and tumor of paratesticular structure (TPS): 4]. We divided a sonographic image into six types for morphological criteria and three types for color Doppler criteria. We examined the relationship between the sonographic classification and histological type.

RESULTS

For morphological criteria, there were 21 cases of Type I (36%), 15 Type II (26%), 9 Type III (15%), five Type IV (9%), five Type V (9%), and three Type VI (5%). For color Doppler criteria, there were 47 cases classified as hypervascular (81%), eight as hypovascular (14%), and three as avascular (5%). Most of the SGCTs were divided into types I and II; the NSGCTs into types III, IV, and V; the LHTs into only type II; and the TPSs into type VI.

CONCLUSION

We established a sonographic classification of testicular tumors with various histological types. This sonographic classification is potentially useful for estimating the histological type of testicular tumors.

摘要

目的

评估我们通过组织谐波成像对睾丸肿瘤进行的超声分类与组织学类型之间的关系。

方法

我们回顾性分析了58例睾丸肿瘤及肿瘤样病变[精原细胞瘤性生殖细胞肿瘤（SGCT）：28例；非精原细胞瘤性生殖细胞肿瘤（NSGCT）：16例；淋巴和造血系统肿瘤（LHT）：7例；Leydig细胞瘤：1例；表皮样囊肿：2例；睾丸旁结构肿瘤（TPS）：4例]。我们根据形态学标准将超声图像分为六种类型，根据彩色多普勒标准分为三种类型。我们研究了超声分类与组织学类型之间的关系。

结果

对于形态学标准，I型21例（36%），II型15例（26%），III型9例（15%），IV型5例（9%），V型5例（9%），VI型3例（5%）。对于彩色多普勒标准，47例分类为高血管（血流丰富）（81%），8例为低血管（血流稀少）（14%），3例为无血管（血流缺失）（5%）。大多数SGCT分为I型和II型；NSGCT分为III型、IV型和V型；LHT仅分为II型；TPS分为VI型。
