Misdiagnosis of Cavernous Angioma Beside Sella Tursica

目的 探讨颅中窝鞍旁海绵状血管瘤的误诊原因 ,提高诊断水平。方法 1985 - 0 1～ 2 0 0 0 - 0 8收治颅中窝鞍旁海绵状血管瘤 2 2例 ,回顾性分析其临床表现和影像学特点。结果 2 2例中术前首要诊断考虑脑膜瘤 8例 ,神经纤维瘤3例 ,垂体瘤 3例 ,脊索瘤 2例 ,胆脂瘤 1例。后经手术及病理证实为海绵状血管瘤 ,误诊率为 77.2 7% (17/2 2 )。结论 鞍旁海绵状血管瘤的临床表现缺乏特异性 ,容易误诊。综合分析患者临床症状 ,影像学检查 ,特别是

Objective To explore the cause of misdiagnosis and improve the diagnostic accuracy of caverous angioma beside sella turcica of middle cranial fossa.Methods Retrospective analysis of the clinical manifestation and the characteristic of photography in 22 cases from 1985 to 2000 was done.Result Of the 22 cases,8 were misdiagnosed as menigioma,3 as neurofibroma,3 as hypophysoma,2 as notochordoma,1 as cholesteatoma. After operation they were diagnosed as caverous angioma by pathology.The rate of misdiagnosis is 77.27%.Conclusion The clinical features of cavernous angioma besidE sella tursica lacks of specificity and is very easy to be misdiagnosed. An synthetic analysis of the clinical signs and photography, especially the character of MRI, must be carry out to reduce misdiagnosis.
