1、《右江民族医学院学报》>2009年12月31卷6期新生儿蛛网膜下腔出血与正常新生儿颅脑的CT鉴别诊断作者:何洪浩 作者单位:广西南宁市红十字会医院放射科,广西南宁530012【摘要】 目的研究新生儿蛛网膜下腔出血(SAH)与正常新生儿颅脑的CT鉴别诊断。方法对比分析85例新生儿SAH与85例正常新生儿的颅脑CT表现,对其影像学特征进行对比分析鉴别。结果85例SAH中发生于直窦27例(31.76%),上矢状窦22例(25.88%),纵裂池14例(16.47%),小脑天幕11例(12.94%),外侧裂池8例(9.41%),脑底池2例(2.35%),小脑延髓池1例(1.18%)。在85例S
2、AH征象中,出现线状征及空三角征49例(57.65%)。85例正常新生儿颅脑相对高密度部位:直窦9例(10.59%),上矢状窦7例(8.24%),纵裂池3例(3.53%),小脑天幕1例(1.18%)。85例SAH患儿,有6例诊断不符。两组CT表现比较差异有显著性(P<0.05)。结论正常新生儿CT表现为直窦、上矢状窦、纵裂池、小脑天幕有时密度相对略高,易误诊为新生儿SAH,因此要注意正常新生儿颅脑与新生儿SAH的CT鉴别。【关键词】 婴儿,新生;蛛网膜下腔出血;体层摄影术,X线计算机;诊断,鉴别CTindifferentialdiagnosisofnewbornsubarachnoidhe
