Brain abscess: A rare complication of catheter: Associated infection in patients on hemodialysis

Abstract

Introduction: Vascular approach is one of the main risk factors that causes infections in patients that are treated by hemodialyses. Brain abscess is one of the rarer metastatic complications of dialytic catheter sepsis. Metastatic infections contribute to the increase of morbidity and mortality rates in hemodialytic patients. Case report: A 38 year-old male patient with the case history of hypertension and a rapid progressive glomerulonephritis treated by hemodialyses who developed brain abscess caused by catheter related complication in the region where he had left-sided parenteral ischemic brain stroke. The admitted patient had no subjective symptoms and neurological deficiency, elevated inflammation parameters. No microorganisms were found after the necessary laboratory analyses, puncture point and catheter tip swab tests. Two weeks after hospital admission the patient's condition deteriorated in terms of an increased number of abscess lesions diagnosed by MRI of endocardium, without clinical impairment and increase of inflammation parameters, so the right choice and duration of parenteral antibiotic administration caused brain abscess regression. Conclusions: Albeit brain abscess is a rare complication of the septic state, physicians should have in mind previous brain lesions, especially in immunosuppressed patients.
