目的探讨25例脊柱包虫病的临床和影像特点、诊断、治疗及误诊原因。方法所有病例经病灶清除手术,部分病例行自体骨、同源异体骨、人工骨或骨水泥填塞。术前及术后口服阿苯达唑(片剂或原粉每日20mg/kg;阿苯达唑脂质体每日10 mg/kg)3个月... 详细信息

目的探讨25例脊柱包虫病的临床和影像特点、诊断、治疗及误诊原因。方法所有病例经病灶清除手术,部分病例行自体骨、同源异体骨、人工骨或骨水泥填塞。术前及术后口服阿苯达唑(片剂或原粉每日20mg/kg;阿苯达唑脂质体每日10 mg/kg)3个月,预防复发。分析其临床、流行病学、影像学及免疫学特点,对诊断、治疗进行总结分析。结果本组18例获得随访,随访时间0.5-15年,平均3.6年;11例复发(6l%),其中颈椎1例,复发3次,胸椎4例,腰椎2例,骶椎4例。25例脊柱包虫中16例有神经症状,Frankel分级A级1例,B级3例,C级3例,D级9例,术后均有不同程度的改善。结论脊柱包虫病X线和CT表现易误诊为结核、转移瘤、骨巨细胞瘤或骨囊肿等, MRI有助于脊柱包虫的诊断与鉴别诊断,血清学检查仍是确诊的主要方法。脊柱包虫病伴脊髓压迫症状采用手术治疗可明显改善症状,但病灶不易彻底清除,即使配合药物化疗也容易复发。

目的探讨影像学对四肢软组织肿瘤的诊断价值。方法54例原发性四肢软组织肿瘤,CT检查23例,MRI31例。结果良性34例、恶性20例。CT检查与病理符合11例,MRI24例;定性错误和未定性,CT12例,MR7例。软组织肿瘤CT的特点是低密度肿块,脂肪瘤、囊肿有典型CT表现;MRI表现各异,脂肪瘤在短T1反转回复(Short-T1WIinver-sionrecovery,STIR)序列具有与皮下脂肪同步降低特点。血管性肿瘤,血管流空信号为其特征性表现。良性肿瘤信号多均匀,边缘规则和光滑。恶性肿瘤呈混杂信号,STIR序列可显示肿瘤浸润性生长的边缘及与正常组织相交形成的移行带,故恶性肿瘤范围>T2WI瘤灶。结论影像学检查对四肢软组织肿瘤诊断有重要价值,CT定性有难度。MRI有一定特征性,结合STIR序列,有助于良恶性鉴别。

目的建立一种操作简单、病变典型、稳定性好的大鼠急性轻症胰腺炎模型。方法大鼠腹腔内分次剂量L-精氨酸注射（3×1g／kg）。注射后6、12、24、48、72h观察血清淀粉酶水平、胰腺病理学改变厦胰腺组织湿／干质量比值的变化。空白对照组以生理盐水代替，6h时处死。结果注射L-精氨酸6h后大鼠即出现典型的急性轻症胰腺炎病理改变，24h达高峰，48h出现少量胰腺细胞坏死，72h病变减轻；胰腺组织湿／干质量比值变化、病理评分呈时相性变化。血清淀粉酶6h时显著增高，24h达高峰，为对照组的3—4倍，72h接近正常水平。结论分次剂量L-精氨酸腹腔内注射诱导的大鼠胰腺炎症改变符合急性轻症胰腺炎病理学的改变，是值得推广的动物模型．
