Monckeberg氏动脉中层钙化硬化（动脉中层钙化）是另一种不重要的硬化形式（动脉粥样硬化和细动脉硬化是两种重要的形式）。在动脉中膜可见紫蓝色的钙化灶，而管腔没有受累。看不到明显临床表现。在老年人的X线上骨盆区可以见到肌层钙化的动脉。
This is Monckeberg's medial calcific sclerosis, which is the most insignificant form of arteriosclerosis (both atherosclerosis and arteriolosclerosis are definitely significant). Note the purplish blue calcifications in the media; note that the lumen is unaffected by this process. Thus, there are no real clinical consequences. Remember this process when calcified muscular arteries show up on a radiograph of the pelvic region in an older person.
