【摘要】：目的:探讨前纵隔原发性恶性肿瘤的MSCT表现,以提高诊断水平。方法:回顾性分析经病理证实的45例前纵隔原发恶性肿瘤患者的影像及临床资料。结果:45例中有胸腺癌17例,病灶中央见囊变坏死,多数肿块囊变坏死区较多、较大;恶性淋巴瘤14例,呈单个不规则形软组织肿块或多个结节相互融合,并包绕大血管生长,多数肿块周围及(或)其他部位见肿大淋巴结;恶性生殖源性肿瘤12例,其中10例尿绒毛膜促性腺激素(HCG)或血甲胎球蛋白(AFP)水平异常,4例见钙化,3例见脂肪成分;恶性孤立性纤维瘤1例,位于前上纵隔偏左侧,内见囊变坏死,三期增强后呈"渐进性"强化;神经内分泌癌1例,边界清,内见囊变坏死,增强后呈环形强化。结论:前纵隔原发性恶性肿瘤的MSCT表现具有一定的特征性,结合临床特点,有助于对其行准确的诊断及疗效评估。
[Abstract]:Objective: to investigate the MSCT findings of primary malignant tumors of anterior mediastinum in order to improve the diagnostic level. Methods: the imaging and clinical data of 45 cases of primary malignant tumors of anterior mediastinum proved by pathology were retrospectively analyzed. Cystic necrosis was seen in the center of the lesion, most of the masses had more dead areas, and 14 cases of malignant lymphoma showed a single irregular soft tissue mass or multiple nodules fused with each other, and wrapped around the large blood vessel growth, 14 cases of malignant lymphoma were found to have a single irregular soft tissue mass or multiple nodules fused with each other. Enlarged lymph nodes were seen around most masses and / or other parts, 12 cases with malignant reproductive tumors, 10 cases with HCG or AFP, 4 cases with calcification and 3 cases with fatty components, were found to be abnormal in urine chorionic gonadotropin (HCG) or blood nail fetal globulin (AFP). One case of malignant solitary fibroma was located on the left side of the anterior superior mediastinal deviation, with cystic necrosis in the mediastinum, "progressive" enhancement after three stages of enhancement, 1 case of neuroendocrine carcinoma with clear boundary, and 1 case with cystic necrosis. Conclusion: the MSCT features of primary malignant tumors of anterior mediastinum have some characteristics, which is helpful to the accurate diagnosis and evaluation of curative effect.
