上期试题：肾、膀胱结核尿液特点是a A．脓尿 B．初血尿 C．中末血尿 D．全血尿 E．以上全不对 ↑右侧顶部硬膜外血肿，少量外伤性蛛网膜下腔出血 CT示：右侧顶部颅骨内板下呈梭形高密度影，边缘清楚、锐利，内部密度均匀，可见少量气体影，局部脑回、脑沟受压向内移位，右侧脑室受压，中线结构左偏，左额部部分脑沟及大脑纵裂池内呈少量高密度影 硬膜外血肿特征表现为颅骨下方双凸形密度，边界非常清楚，一般不超过颅缝，可有骨折。有时急性胸膜下血肿亦可见梭形高密度影，两者鉴别较难，通常硬膜外血肿范围较局限，多伴有颅骨骨折，有助于区别。CT和MRI均匀确诊意义，急性期首选CT，但对 慢性和亚急性期血肿的显示，MRI优于CT。 Epidural hematoma characteristics of skull bottom double convex density, boundary is very clear, is generally not more than cranial seam, can be broken. Sometimes acute subpleural hematoma are visible spindle high density shadow, both identification more difficult, in a relatively limited scope of epidural hematoma, accompanied by a skull fracture, helps the difference. CT and MRI diagnosis significance of acute phase for CT, but the chronic and subacute phase of hematoma, MRI is superior to CT. 本期试题：硬膜外血肿的好发部位在？ A．额部 B．颞部 C．顶枕部 D．顶部 E．矢状窦旁 |
