Calcification in Craniopharyngiomas

Preliminary Study on Composition and Microstructure of Calcification in Craniopharyngiomas

Abstract

To analyze the element composition and microstructure of calcification in craniopharyngiomas and to explore the differences among differing degrees of calcification, 50 consecutive patients with craniopharyngioma were selected. X-ray diffraction analysis and energy-dispersive X-ray spectroscopy analysis were performed on the calcified plaques isolated from the tumor specimens. All calcified plaques were constituted of hydroxyapatite crystals and some amorphous materials. The main elements for the analysis were calcium, phosphate, carbon, and oxygen. There were significant differences among groups of differing degrees of calcification in the percentage composition of calcium, phosphorus, and carbon (P < 0.05), in which the element content of calcium and phosphorus had a positive correlation with the extent of calcification (rp = 0.745 and 0.778, respectively, P < 0.01), while the element content of carbon had a negative correlation with the extent of calcification (rp =-0.526, P
