CT scan of the chest (November, 2003): A tumor size is 2.6 cm×3.1 cm at superior lobe close the hilum of right lung but the boundaries between the big vessels of the gate is clear, the regular margin of the neoplasm could be observed without burr and the density is uniform, CT value is of 23 Hu.
CT检查(2003年11月):右上叶近肺门处软组织密度灶2.6 cm×3.1 cm,形态尚规则,密度均匀,边缘光整、无毛刺,与肺门、大血管境界清晰,CT值23 Hu。CT scan of the chest (November, 2003): A tumor size is 2.6 cm×3.1 cm at superior lobe close the hilum of right lung but the boundaries between the big vessels of the gate is clear, the regular margin of the neoplasm could be observed without burr and the density is uniform, CT value is of 23 Hu.2005年2月,患者因劳动时出现咳嗽、痰中带血就诊。CT检查示右上叶肺周边部软组织影,大小为9.5 cm×12.8 cm,分叶状、部分短毛刺,外侧缘贴近壁层胸膜,内侧缘与肺门结构分界不清,平均CT值24 Hu(图 2),影像学诊断为中央型晚期肺癌。纤维支气管镜检查:右支气管开口处轻度狭窄、腔内光滑无新生物,刷检阴性。1周后,应患者要求剖胸探查。术中见右上肺实质性肿块与壁层胸膜、肺门、心包粘连,锐性清除肺门、隆突下淋巴结,行右全肺切除。巨检显示右上肺包膜下浅灰白色肿块10.1 cm×13.2 cm,质脆嫩、易碎,剖面上见部分包膜,并有少部分壁层胸膜附着(图 3A); 镜下显示恶性异形小细胞腺样排列,间质以梭形、原始间叶细胞为主,呈散在性分布,部分向软骨方向分化(图 3B,图 3C); 免疫组化为Vimentin(++)、EMA(+); 病理诊断为经典肺母细胞瘤。
CT scan of the chest (February, 2005): A tumor size is 9.5 cm×12.8 cm at the superior lobe, its lateral edge closes the pleura and the adhesion to the chest wall is seen, the inside edge closes to the hilum of right lung and the boundary is not clear, the lobulated and blurry verge of the neoplasm could be observed with short burr, CT value is of 24 Hu.
Pathological diagnosis: a pulmonary blastoma (biphase-type). A: The tumor is solitary within the lung and clinging to the visceral pleura where encroachment of a part of parietal pleura occurred and with fragile and grayish white cross section. The maximum tumor size is 10.1 cm×13.2 cm. B, C: Microphotograph is showing the malignant mesenchymal cells presented with a dispersed distribution being given priority to spindle primitive mesenchymal cells, and there are glandular organelles formed by the malignant epithelial cells. The differentiated cartilage could be seen (HE, ×200).

Postoperative CT scan of the chest. A, B (March 2005): After right pneumonectomy, the pleural effusion is on the right side, shadow of the chest drainage tube section is seen; C, D (May 2013): After right pneumonectomy, the mediastinum has been moved to the right with right chest collapsed. There is no expression of the tumor relapse or metastasize.
术后CT。A、B:右全肺切除术后,右侧胸腔积液、见引流管截面影(2005年3月); C、D:纵隔右移,右侧胸廓塌陷,右全肺切除术后所见,未见肿瘤复发、转移征像(2013年5月)。Postoperative CT scan of the chest.
