Abstract

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 whom 16 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.
