| 目的 观察原发性卵黄囊瘤患者的CT表现。方法 回顾性分析经病理证实的31例原发性卵黄囊瘤的临床及CT表现，其中8例仅接受CT平扫，23例接受CT平扫及增强扫描。结果 19例肿瘤位于性腺，包括单侧卵巢11例，睾丸8例；12例肿瘤位于性腺外，包括骶尾部7例，前纵隔3例，阴道2例。20例肿瘤呈椭圆形，11例形态不规则；20例肿瘤边界相对清楚，11例边界模糊；2例合并畸胎瘤，瘤内可见脂肪、钙化。增强扫描示23例肿块实性部分呈中度至明显强化，17例呈丝瓜瓤样强化，18例可见供血血管，21例病灶边缘见延迟强化的包膜；4例显示肿瘤包膜破裂。结论 卵黄囊瘤CT表现具有一定特征性，可为诊断提供影像学依据。 |

| Objective To investigate the sonographic features and to analyze misdiagnosis causes of intrascrotal adenomatoid tumors. Methods Preoperative sonographic data of 15 patients confirmed as intrascrotal adenomatoid tumor by surgery and pathology were retrospectively analyzed. Compared with pathological results, the sonographic features and the misdiagnosis causes were analyzed. Results Among 15 patients, the tumors located at the tail of epididymis in 8 patients, at the head of epididymis in 5 patients and within the testis in 2 patients. The lesions were misdiagnosed as inflammatory diseases in 3 patients, as cysts in 3 and as malignant tumors in 2 patients, while in the others were indeterminate. Solid tumors were detected with ultrasound in 12 patients, while cystica in 3 patients. Among 12 patients with solid tumors, lesions in 7 patients had clear boundary and regular shape, while the boundary in the rest 5 patients were less clear. The internal echo was homogeneous in 6 patients and inhomogeneous in the rest 6 patients with echoless and punctate hyperecho. Cystic mass was characterized by polycystic with isolation belt. Among 15 patients of intrascrotal adenomatoid tumor, detectable blood flow signals were found in 8 patients, while no obvious blood flow signals were found in the rest 7 patients. Conclusion Ultrasonic features of intrascrotal adenomatoid tumor were less characteristic. Combination of clinical information and other imaging findings might help to decrease misdiagnosis. |
