摘要
作者报道39例由颅内占位性病变而具有钙化斑的病人,根据CT所见,提出被此鉴别的要点。用腐烂和剥离法取出标本中的钙斑,以光镜和扫描电镜对其做了观察,见到随病变性质不同而钙斑的形状结构也不同。5例钙斑还以扫描电镜能谱仪进行了成份分析,结果是:所有钙化斑除含有钙磷外,还含有硅,而其他成份如钾、镁、铁、硫等则是可有可无。为何在病变处出现钙质增多?经讨论后认为,那可能是免疫或其他反应的伴随现象,有助于限制病变的发展或向良性方面转化。
39 cases of intracranial space-occupying lesion with calcification plaque are reported.Based on the examination with CT scan,some points for differential diagnosis were proposed. By rottening and stripping the calcified plaque picked out from the specimen and examined with light and scanning electron microscope.The shape and structure of the calcified spots varied according to the pathological changes.The chemical composition of the calcification in 6 cases were analysed with EDX. Except calcium or phosphorus,it also contain silicone; but some other composition like potassium, magnesium, iron, sulfus etc may or may not present.Why the calcified materiales are deposit around or in the pathological focus? It is assumed to be one accompanying that may he the effect of immunological, which try to restrict the progress of the illness or to transform it into benign status.
