脑脓肿的脑脊液变化与脓肿的部位、病期、大小、感染的来源、病原菌特性、单发或多发、距离脑表或脑室的远近、有无溃破或并发脑膜炎,以及抗菌素的使用等有关.外观脑脊液可澄清,也可混浊或呈脓性,特别是脓肿破入脑室或蛛网膜下腔时.若脑脊液细胞数超过300/mm~3时,肉眼可见混浊.压力腰穿压力常增高,特别是位于后颅凹和脑室附近的脓肿,或脓肿溃破而并发急性化脓性脑膜炎时压力增高更为显著.Kiser和Kendig报告3/4的脑脓肿患者腰穿压力不超过250mmH_2O.Bonnal报告326例脑脓肿患者中仅93例有颅内压增高症状.
Brain abscess cerebrospinal fluid changes and abscess location, duration, size, source of infection, pathogens, single or multiple, distance from the epicardium or ventricle, with or without ulceration or meningitis, and the use of antibiotics, etc. Appearance of cerebrospinal fluid can be clarified, can also be cloudy or was purulent, especially abscess break down into the ventricle or subarachnoid space if the number of cerebrospinal fluid cells over 300 / mm ~ 3, visible to the naked eye oppression pressure lumbar pressure is often increased, Especially in the posterior fossa and near the abscess or abscess ulceration complicated acute acute purulent meningitis increased pressure when Kiser and Kendig reported 3/4 brain abscess patients with pressure less than 250mmH_2O.Bonnal report Only three of 326 patients with brain abscess had symptoms of increased intracranial pressure.
