目的:分析小细胞肺癌(small cell lung cancer,SCLC)的CT表现特点,以提高对该病的认识。方法:收集有CT和临床资料并经病理证实的SCLC 60例,回顾性总结分析CT影像特征。结果:中央型肺癌47例,CT表现为肺门分叶状结节或肿块,伴阻塞性肺炎11例(23.4%),阻塞性肺不张5例(10.6%),42例(89.4%)伴有纵隔淋巴结肿大,36例行CT增强,其中32例肿块和淋巴结均匀强化。13周围型SCLC中,9例肿大的肺门、纵隔淋巴结较肺内肿瘤大。结论:SCLC CT主要征象以肺门区实性肿块为主,多伴有肺门、纵隔淋巴结转移,支气管阻塞征象出现较晚。
目的:探讨鼻咽纤维血管瘤术前栓塞的应用价值。方法:17例鼻咽纤维血管瘤患者,单纯手术摘除10例,术前3天进行数字减影血管造影(DSA)检查及血管内栓塞术7例。结果:7例术前栓塞组术中出血200～700mL,平均430mL;输血0～550mL;10例单纯手术组出血550～1430mL,平均1200mL,输血350～1200mL。术前栓塞组出血量和输血量较单纯手术组显著减少。结论:术前瘤体栓塞治疗鼻咽纤维血管瘤是安全有效、理想的术前辅助治疗手段。
【摘要】 目的 探讨系统性红斑狼疮脑病（SLEE）的磁共振成像（MRI）特征和诊断价值。 方法 回顾性分析2007年1月-2009年7月间18例SLEE的临床表现及MRI特征。 结果 18例患者MRI检查的颅脑阳性率为88.88%（16/18），脑部MRI表现为:①15例为多发病灶，局灶者1例。②双侧大脑半球、基底节区及小脑半球脑实质内长T1、长或稍长T信号，DWI及EPI成像上呈高或稍高信号，灰白质均可受累，分布无规律性。③增强MRI扫描9例，其中5例呈斑片状强化，4例无明显强化。④脑梗死12例，脑出血4例。合并脑水肿9例，脑萎缩7例。 结论 SLEE的MRI表现多样，结合临床资料，MRI可以作出诊断。【Abstract】 Objective To investigate the magnetic resonance imaging (MRI) features of systemic lupus erythematosus encephalopathy (SLEE) and its diagnostic value. Methods The clinical data and MRI images of 18 patients with SLEE admitted from January 2007 to July 2009 in our hospital were analyzed retrospectively. Results Positive findings were found in 16 patients (88.88%). MRI findings of SLEE were the following: ①A Total of 15 patients were with diffuse lesions, one patient was with focal lesions. ②Cerebral hemisphere involvement and bilateral caudate long T1 and long or slightly long T2 signal were intensive in the brain parenchyma, and appeared as hyper-intensity or slightly hyper-intensity on DWI and EPI. Grey and white matters were involved often and irregularly distributed. ③The results of 9 patients by enhanced MRI showed that 5 patients were with patchy enhancement and 4 were without enhancement. ④Of the 16 positive patients, 12 were with cerebral infarction and 4 with cerebral hemorrhage, while 9 patients were complicated with cerebral edema, and 7 patients were with cerebral atrophy. Conclusion MRI manifestations of SLEE are various. Combined with clinical data, MRI can diagnose SLEE exactly.
目的:探讨单发脑转移瘤的CT和MRI诊断价值。方法:回顾性分析37例经手术病理证实或临床综合诊断确诊的单发脑转移瘤的CT和MRI表现。结果:病灶位于幕上31例,分布于皮髓质交界区21例。囊实性22例,实性9例,囊性6例。不规则环形强化13例,结节形强化7例,囊实形强化15例,均匀强化2例。病灶直径gt;1.0 cm时瘤周水肿常较明显。结论:单发脑转移瘤的CT、MRI表现具有一定的特征,增强扫描对诊断单发脑转移瘤有重要价值。
