图示副脾，其实并不罕见。虽然，副脾不但有正常脾脏的表现，也可出现“脾组织种植”的情况，即当脾破裂时，部分脾（多由于外伤）种植在腹膜表面并发挥其功能。
Here is an example of an accessory spleen. These are not that uncommon and are really incidental findings. Remember, though, that the accessory spleen can undergo all changes that the larger spleen can. There is also a condition known as "splenosis" which occurs when portions of disrupted spleen (usually from trauma) implant on peritoneal surfaces and continue to function.
