RESUMEN
We describe a case of brain abscess which developed in a 64-year-old man after hepatic artery chemoem-bolization(HACE) for hepatocellular carcinoma(HCC).On his first admission, percutaneous liver biopsy led to a diagnosis of type-C liver cirrhosis, he readmitted 5 years later and HCC was diagnosed. The patient underwent two HACE procedures, with a two-month interval. Three month later, he was readmitted to hospital with headache and brief loss of consciousness; brain magnetic resonance imaging(MRI) revealed a brain abscess. Stereotactic aspiration was performed and antibiotics sensitive to the klebsiella pneumonia bacteria cultured in the abscess were administrated intraveously. One month later, the abscess size became smaller and the patient was discharged. This report reviews the literature and discusses the pathogenesis of brain abscess after intra-arterial embolization.
