The calcification in a totally calcified pineal tumour was studied. Transmission electron microscopy indicated that the tumour was a pinealoma. The type of calcification was investigated by bright-field and dark-field transmission electron microscopy in addition to electron diffraction and electron-induced x-ray fluorescence. The calcified material consisted predominantly of amorphous calcium phosphate. The type of calcification differs from the normal calcification present in pineal acervuli which consists of crystalline hydroxypatite.
对一个完全钙化的松果体肿瘤中的钙化进行了研究。透射电子显微镜检查表明该肿瘤是松果体瘤。除了电子衍射和电子诱导X射线荧光外，还通过明场和暗场透射电子显微镜研究了钙化的类型。钙化物质主要由无定形磷酸钙组成。这种钙化类型不同于松果体凝块中存在的正常钙化，后者由结晶性羟基磷灰石组成。
