Abstract：
BACKGROUND: Nosocomial infections caused by Serratia marcescens mostly occurred in pediatrics and it was very rarely reported after adult surgery. Here, an intracranial abscess caused by Serratia marcescens was reported. We report a rare case of a postoperative intracranial abscess caused by Serratia marcescens in a 63-year-old male patient with a left parietal mass. The patient underwent resection of the mass on June 1, 2022, and the postoperative pathology revealed an angiomatous meningioma, WHO I. He then experienced recurrent worsening of right limb movements, and repeated cranial CT scans showed oozing blood and obvious low-density shadows around the operation area. Delayed wound healing was considered. Subsequently, a large amount of pus was extracted from the wound. The etiological test showed that Serratia marcescens infection occurred before the removal of the artificial titanium mesh. Antibiotics were initiated based on the results of drug susceptibility tests. At present, the patient is recovering well and is still closely monitored during follow-up.
CONCLUSIONS: It is rare for Serratia marcescens to cause brain abscesses without any obvious signs of infection. This report provided in detail our experience of a warning postoperative asymptomatic brain abscess caused by an uncommon pathogen.

摘要：
背景：粘质沙雷氏菌引起的医院感染主要发生在儿科，成人手术后很少报道。这里,据报道，由粘质沙雷菌引起的颅内脓肿。我们报告了一例罕见的由粘质沙雷氏菌引起的术后颅内脓肿，该病例为63岁的男性患者，患有左顶叶肿块。该患者于2022年6月1日进行了肿块切除术，术后病理显示为血管瘤性脑膜瘤，WHOI.然后他经历了右肢体运动的反复恶化，重复的头颅CT扫描显示手术区域周围有明显的渗血和低密度阴影。考虑了延迟的伤口愈合。随后，从伤口中提取了大量的脓液。病原学检测显示，粘质沙雷菌感染发生在人工钛网切除前。根据药敏试验结果开始使用抗生素。目前,患者恢复良好，在随访期间仍受到密切监测。
结论：粘质沙雷菌很少引起脑脓肿，但没有任何明显的感染迹象。该报告详细提供了我们对由罕见病原体引起的警告术后无症状脑脓肿的经验。
