Circumscribed pink areas 0.3-1.0 cm in diameter seen in deeper parts of otherwise well-fixed brains are usually ascribed to inadequate fixation. Twenty-three patients with pink areas in their fixed brains had evidence of inflammation in at least one organ. Blood vessels in the pink areas contained bacteria. Postmortem cultures identified the organisms in 16 cases. Gram-negative bacteria were the most common. Sharply delineated pink areas in well-fixed brains correlate with postmortem intravascular growth of bacteria.
在原本固定良好的大脑较深层部位可见直径为0.3 - 1.0厘米的边界清晰的粉红色区域，通常归因于固定不充分。23例固定大脑中有粉红色区域的患者至少有一个器官存在炎症迹象。粉红色区域的血管中含有细菌。尸检培养在16例中鉴定出了微生物。革兰氏阴性菌最为常见。在固定良好的大脑中界限分明的粉红色区域与死后细菌在血管内生长有关。
