摘要
目的:分析睾丸原发肿瘤的CT影像特征。方法:回顾性分析46例经病理证实的睾丸肿瘤CT影像资料,结合其他资料对病灶做综合评估。结果:所有肿瘤均为单侧发病。精原细胞瘤24例,其中16例可见不均匀轻度分隔样强化;内胚窦瘤10例,8例可见多发迂曲、增粗供血血管;畸胎瘤4例,可见斑点状、不规则钙化,2例可见脂肪;混合性生殖细胞肿瘤2例,增强扫描明显不均匀强化,可见迂曲、增粗血管影,未见钙化及脂肪;平滑肌瘤2例,边界清晰,密度均匀,增强扫描轻度均匀强化;弥漫大B细胞淋巴瘤3例,2例边界清晰,密度均匀,增强扫描中度强化,1例局部边界不清,增强不均匀强化;恶性间质细胞瘤1例,可见粗大钙化,实性成分中度强化,伴腹膜后淋巴结及双肺转移。结论:对于不同类型睾丸肿瘤CT有较好的鉴别能力,能为临床治疗方案提供较为准确的依据。
Objective:To analyze the imaging features of primary testicular tumor.Methods:The CT imaging data of 46 cases of testicular tumor confirmed by pathology were retrospectively reviewed.Combined with the other data,the location,attenuation,size,shape,edge,and enhancement patterns of lesions were comprehensively analyzed.Result:All 46 cases of testicular tumor were unilateral.There were 24 cases of seminoma,among whom16 cases showed uneven mild septal enhancement;10 cases of endodermal sinus tumor,and 8 cases showed multiple tortuous and thickened blood vessels;4 cases of teratoma,spot or irregular calcification;2 cases of mixed germinoma,obvious heterogenous enhancement with no calcification or fat;2 cases of leiomyoma with clear border,homogeneous density and nhomogeneous enhancement in enhanced scan;3 cases of diffuse large B cell lymphoma,2 cases showed clear boundary,uniform density and homogeneous enhancement,1 case of patchy low density area,with unclear boundary,persistent enhancement,the low density area showed no enhancement;1 case of malignant mesenchymal cell tumor with thick calcification and moderate enhancement of solid components,accompanied by retroperitoneal lymph node and lung metastasis.Conclusion:CT can distinguish the imaging features of different types of testicular tumors,and have high value in the diagnosis and differential diagnosis of testicular tumors.Thus CT can provide a more accurate basis for clinical treatment.
