  • The CT Diagnosis of Thymic Carcinoid and the Literature Review

    目的:总结胸腺类癌的临床表现、病理特征、CT表现及其临床价值。方法:对本院收治的2例胸腺类癌进行分析并结合文献复习。结果:胸腺类癌发病率低,大部分早期患者无临床症状,经胸部X线、CT检查时发现;中晚期始出现症状。病理检查出类癌后,电镜可见神经内分泌颗粒,免疫组化显示神经特异性烯醇化酶、肿瘤嗜铬蛋白A、促皮质素阳性。胸部CT表现特征为起于前上纵隔肿块,常位于心底部大血管和心包周围,肿块内密度不均,可见钙化,增强后轻中度强化,易发生胸内外转移。结论:胸腺类癌是一罕见的前纵隔肿瘤,根据CT特征,结合临床可有助诊断、指导手术、推测预后,因此CT在临床诊治中有非常重要的价值。

  • Multi slice CT spiral and MRI Performance of Spinal Giant Cell Tumor (6 Cases’ Reports)

    目的:明确脊柱骨巨细胞瘤的多层螺旋CT、MRI表现。方法:回顾性分析经病理证实的脊柱骨巨细胞瘤6例(男5例,女1例,年龄21~40岁,平均32岁)。6例CT检查,3例有MRI检查。结果:发生于胸椎3例,腰椎1例,骶椎2例。CT主要表现为膨胀性溶骨性破坏和较大软组织肿块;MRI表现T1加权成像为低等信号,T2加权成像为高低混杂信号特点,可显示瘤内坏死、囊变、出血等。结论:脊柱骨巨细胞瘤具有侵袭性强、生长活跃、易复发等特点,结合CT、MRI检查可对该病做出及时诊断,且对临床分期、手术方案制订及术后定期随访有重要价值。

  • Dominant distribution and pathological basis of thin layer 16-slice spiral CT signs of coal workers’ pneumoconiosis

    Objective To clarify the thin-layer 16-slice spiral CT features of coal worker’s pneumoconiosis and the superior distribution of comorbidities in their staging and lobes and lung field anatomy. Methods Sixty-six patients with coal worker's pneumoconiosis diagnosed by the pneumoconiosis diagnosis and identification group from October 2014 to March 2015 were enrolled. All patients underwent 16-slice spiral CT and thin-layer CT reconstruction with a thickness of 1.5 mm. The thin-slice CT signs and comorbidities of coal workers’ pneumoconiosis were observed, and the superior distribution of CT signs in patients at different stage and different lobes and lung field anatomy were evaluated. Results There were 16 cases of irregular small nodules in the lungs, 22 cases of large shadow fusion, 18 cases of intraocular shadow calcification, 41 cases of emphysema, 21 cases of pulmonary bullae, 21 cases of pulmonary hypertension, and 31 cases of enlarged lymph nodes in the mediastinum and calcified. The above signs were mostly distributed in stage Ⅲ pneumoconiosis (P<0.05). There were 32 cases of regular small nodules, which were mostly distributed in stage Ⅰ pneumoconiosis. In the 16 cases of irregular small nodules, the advantage was distributed in the middle and outer lobes of the double lungs. In the 22 cases of large shadow fusion, the advantage was distributed in the upper and lower lobe of the lungs. In the 16 cases of tuberculosis, the advantage was distributed in the upper lobe of the lungs. In the 21 cases of bullous bullae, the advantage was distributed in the upper lobe of the two lungs, mostly in the right upper lung. Conclusion The thin 16-slice spiral CT signs of coal worker’s pneumoconiosis can reflect the pathological changes, and have a certain correlation with the stage of pneumoconiosis, and have obvious characteristics in the anatomical distribution of lung and lung fields.
