CT examination of the testes was carried out in 49 patients for the investigation of testicular tumours. Hypodensity and inhomogeneity were typical of teratomas and hyperdensity and relative homogeneity of seminomas. Granulomatous orchitis and lymphomas showed the same characteristics as seminomas. Three testes in the abdomen could be localised and classified. One non-palpable primary tumour was found as well as an old partially calcified tumour, three old torsions and one lipo-sarcoma. In about 10% it was not possible to distinguish between tumour and inflammatory lesions. Compared with sonography, CT has advantages, particularly in the diagnosis of old torsion.
对49例患者进行了睾丸CT检查以排查睾丸肿瘤。畸胎瘤的典型表现为低密度和不均匀性，精原细胞瘤则为高密度和相对均匀性。肉芽肿性睾丸炎和淋巴瘤与精原细胞瘤表现出相同特征。可对腹部的三个睾丸进行定位和分类。发现了一例无法触及的原发性肿瘤以及一例陈旧性部分钙化的肿瘤、三例陈旧性扭转和一例脂肪肉瘤。约10%的病例无法区分肿瘤和炎性病变。与超声检查相比，CT具有优势，尤其是在诊断陈旧性扭转方面。
