Brain abscess as a rare complication in a hemodialysed patient.
BACKGROUND
Infections remain among the most common morbid events and are an important cause of death in end stage renal disease. They have reduced immune response and increased hazard of infections due to repeated puncture of an arterio-venous fistula, formation of haematoma at the site of cannulation and central vein catheterisation.


METHODS
We report a case of brain abscess in chronically haemodialysed patient admitted to our department due to haedache, vomiting, accelerated hypertension and fever. The clinical examination revealed narroving of the right palpebral slit, weeping and right oral angle hanging loose. He had mild microcytic anaemia and high level of g-globulin. Ophtalmologic examination showed normal oculi fundi. The computed tomography revealed heterogenous mass marginally enhanced with contrast agent in the right frontal cerebral lobe. The right fronto-temporal craniotomy was performed and the right frontal lobe abscess was found and totally excised. The postoperative course was uneventful besides of seizures which were effectively treated with carbamazepine. After bilateral nephrectomy the patient undervent succesfull kidney transplantation and is in good condition without any neurological defect. A probable cause of his brain abscess was peridontal abscess recognized 3 month earlier or bilateral vesicoureteral refluxes.


CONCLUSIONS
1. Uremic patients have a reduced immunocapacity and are a high risk group for infections of various etiology. 2. Prompt eradication of all sources of infection is essential in hemodialysed patients.
