【摘要】：目的探讨胸腺神经内分泌肿瘤(neuroendocrine tumors of the thymus,NETT)的临床及CT表现。方法回顾分析9例病理确诊NETT患者临床及CT图像,并结合相关文献复习。结果男性8例,女性1例,平均年龄57.4岁,临床无特异性,病理不典型类癌5例,小细胞癌3例,大细胞癌1例。CT表现前上纵隔体积较大实性肿块,平均最大经为8.6cm,7例见坏死,2例见钙化,均具有侵袭性特点,7例侵及邻近胸膜,3例侵及血管,增强呈中度不均匀强化,6例瘤内见细小血管强化影,8例合并纵隔淋巴结肿大,4例发生转移。结论 NETT以中老年男性多见,具有体积大、易坏死、明显侵袭性、不均匀强化、常见瘤内细小血管强化影、易淋巴转移等特点,CT有助于提高NETT的准确诊断率,明确受侵范围,指导手术方案。
[Abstract]:Objective to investigate the clinical and CT findings of neuroendocrine tumors of the thymuscus nettt (NETT) in thymic neuroendocrine tumors. Methods the clinical and CT images of 9 patients with pathologically confirmed NETT were retrospectively analyzed. Results there were 8 males and 1 female with an average age of 57.4 years. There were 5 cases of atypical carcinoid, 3 cases of small cell carcinoma, 1 case of large mass of mediastinum on CT scan, 5 cases of atypical pathological carcinoid, 3 cases of small cell carcinoma, and 1 case of large solid mass of mediastinum before CT. The average maximum meridian was 8.6 cm ~ (-1) in 7 cases, necrosis in 2 cases, calcification in 2 cases, and invasion of adjacent pleura in 3 cases. In 6 cases with moderate heterogeneous enhancement, 8 cases with mediastinal lymphadenopathy and 8 cases with mediastinal lymph node enlargement and metastasis were found in small vessel enhancement. Conclusion NETT is more common in middle-aged and elderly men, with the characteristics of large volume, easy necrosis, obvious invasion, uneven enhancement, small vessel enhancement in common tumor, easy lymphatic metastasis and so on. The CT scan is helpful to improve the accurate diagnosis rate of NETT and to determine the extent of invasion. To guide the operation plan.
