Cases had coarse long spiculation and among them 7 cases were irregular sharps or triangular and polygonal sharps. 粗长毛刺征9例,其中7例病灶形态呈不规则形和三角、多角形;
Significance of pathologic examination of small peripheral lung cancer spiculation on target blockout 周围型小肺癌毛刺病理学检查对靶区勾画的意义
It contains ( 1) margin of lesions, spiculation is significant malignant features. ( 2) Enhancement of lesions can not singly differentiate fibroadenoma and breast cancer. 病灶的边缘是否毛糙、有尖角、有毛刺,是考虑恶性的重要征象。(2)增强对纤维腺瘤及乳腺癌两者单独较难鉴别。
Objective To study the evaluation of spiculation sign in the diagnosis and differential diagnosis of solitary pulmonary nodule(≤ 3 cm). 目的探讨毛刺征对肺孤立结节(≤3cm)的诊断与鉴别诊断价值。
The edge of the lesions presented long and thick spiculation. 病灶边缘粗长毛刺。
Purpose: To evaluate the CT manifestations, diagnosis value and multiplanar reconstruction ( MPR) detection of spiculation in small peripheral lung carcinoma ( SPLC). 目的:探讨周围型小肺癌(SPLC)毛刺的CT表现、诊断价值及多平面重建(MPR)的检出作用。
Results Most peripheral small lung cancer appeared as nodule, their average diameter was 17 mm. 9 cases showed homogeneous density and another 9 cases were appeared as aggregation by small multi-nodule. 6 cases were slight lobulated and another 6 cases had short spiculation. 结果周围型肺癌多以小结节形式出现,平均直径17mm,9例密度均匀,9例呈多结节融合状,6例边缘呈浅分叶,6例边缘有短细毛刺。
The deep lobulation, short fine spiculation, spine, vacuole sign and air bronchograms were more appeared in lung cancers. 深分叶、短细毛刺、棘状突起、空泡征及支气管气象多见于肺癌。
Conclusion: Spiculation has the higher value in diagnosing and differentiating SPLC. 结论:毛刺征对SPLC的诊断和鉴别诊断具有较高价值。
Pulmonary metastasis did not contain bronchi, their margin without spiculation, but bronchial branches were compressed and shifted forming "holding ball" shape. 肺转移瘤内不含有支气管,边缘无毛刺,但压迫支气管支呈握球样。
NSCLC with CT characteristics of lobulation, spiculation, pleural invasion and lymph node metastases showed higher invasion and poorer prognosis. 有分叶征、毛刺征、胸膜浸润和纵隔淋巴结增大的肺癌CD44v6高表达而E-cad失表达,提示具有较强的侵袭转移潜能,预后较差。
Lobulation, long and stiff spiculation and sawtooth interface were imaging characteristic in their margin. 病灶边缘以分叶征、星芒状毛刺、界面锯齿征为主要特征;
Ultrasound indicators included tumor size, shape, ratio of the longest/ shortest dimension, edge of the spiculation and hyperechoic halo sign, internal echo types, microcalcification, posterior echo types, blood flow and signs of lymph node metastasis. 超声观察指标主要包括肿块的大小、形态、纵横比、边缘毛刺及周边高回声晕征、内部回声、微钙化、后方回声、血流及淋巴结转移等征像。
