Intracranial abscesses are uncommon, serious and life-threatening infections. A brain abscess is caused by inflammation and collection of infected material, coming from local or remote infectious sources. Patients with chronic kidney disease on dialysis are prone to invasive bacterial infections like methicillin-resistant (MRSA) especially in the presence of central venous catheters or arteriovenous grafts. However, intracranial abscess formation due to MRSA is rare. Here, we present a case of MRSA brain abscess with an atypical clinical presentation in the absence of traditional risk factors.Intracranial abscesses are uncommon, serious, and life-threatening infections. A Brain abscess is caused by inflammation and collection of infected material, coming from local or remote infectious sources. Patients with chronic kidney disease on dialysis are prone to invasive bacterial infections like methicillin-resistant staphylococcus aureus (MRSA) especially in the presence of central venous catheters or arterio-venous grafts. However intracranial abscess formation due to MRSA is rare. Here we present a case of MRSA brain abscess with an atypical clinical presentation in the absence of traditional risk factors. A 46-year-old male with chronic kidney disease (CKD) secondary to chronic glomerulonephritis, on haemodialysis for 4 years through a left brachio-cephalic AVF developed an episode of generalised tonic-clonic seizures lasting 2 min during his scheduled dialysis session. He reported no complaints before entry to the dialysis. On clinical examination, he was drowsy with the absence of any focal motor deficits. His blood pressure was recorded to be 200/120 mm Hg. He was managed in the intensive care unit with mechanical ventilation, intravenous nitroglycerine for blood pressure control, levetiracetam for seizures and empirical vancomycin. Radiological evaluation showed a brain abscess in the midline involving bosth basi-frontal lobes. After medical optimization, the abscess was drained surgically, and the pus cultured. As culture grew Methicillin Resistant Staphylococcus aureus, he was treated with intravenous vancomycin for 6 weeks. On follow up, the abscess had resolved and the patient recovered without any neurological deficits.
颅内脓肿并不常见,但却很严重,甚至危及生命。脑脓肿是由炎症和感染物质聚集引起的,这些感染物质来自局部或远处的感染源。接受透析的慢性肾脏病患者容易发生侵袭性细菌感染,如耐甲氧西林金黄色葡萄球菌(MRSA),尤其是在存在中心静脉导管或动静脉移植物的情况下。然而,由于 MRSA 引起的颅内脓肿形成较为罕见。在此,我们报告了一例无典型危险因素的 MRSA 脑脓肿病例,其临床表现不典型。颅内脓肿并不常见,但却很严重,甚至危及生命。脑脓肿是由炎症和感染物质聚集引起的,这些感染物质来自局部或远处的感染源。接受透析的慢性肾脏病患者容易发生侵袭性细菌感染,如耐甲氧西林金黄色葡萄球菌(MRSA),尤其是在存在中心静脉导管或动静脉移植物的情况下。然而,由于 MRSA 引起的颅内脓肿形成较为罕见。在此,我们报告了一例无典型危险因素的 MRSA 脑脓肿病例,其临床表现不典型。一名 46 岁男性,因慢性肾小球肾炎导致慢性肾脏病(CKD),在左头臂静脉动静脉瘘接受 4 年血液透析时,在计划透析期间发生持续 2 分钟的全身性强直阵挛性癫痫发作。他在进入透析前没有任何不适。临床检查时,他表现为昏睡,无任何局灶性运动缺陷。他的血压记录为 200/120mmHg。他在重症监护病房接受机械通气、静脉硝酸甘油控制血压、左乙拉西坦控制癫痫发作和经验性万古霉素治疗。影像学评估显示中线脑脓肿累及双侧额底叶。在进行医疗优化后,脓肿被手术引流,脓液被培养。由于培养出耐甲氧西林金黄色葡萄球菌,他接受了 6 周的静脉万古霉素治疗。随访时,脓肿已消退,患者无任何神经功能缺损而康复。
