观察分析16例基底节假性钙化,结果表明,全部发生于苍白球。除1例伴有少量钙盐外,其余全部为铁,临床和化验检查未见异常,发生率随年龄增长而增加。因此,认为基底节假性钙化系生理性的。铁沉积继发于血管外膜增厚,铁可能来自血管周围脑组织。故推测血管外膜增厚可能是在渗出物基础上,继而发生机化,最后胶原化所致。 Observation and analysis of 16 cases of basal ganglia calcification, the results showed that all occurred in the globus pallidus. Except for 1 case accompanied with a small amount of calcium salt, the rest were all iron, no abnormalities were found in clinical and laboratory tests, and the incidence increased with age. Therefore, the basal calcification is assumed to be physiologically. Iron deposition secondary to vascular thickening, iron may come from perivascular brain tissue. It is speculated that thickening of vascular adventitia may be based on the exudate, and then the occurrence of mechanization, the last collagen.
