[Brain abscess in congenital cyanotic heart defect in adulthood].

A 27-year-old patient with pulmonary atresia, ventricular septal defect, and multifocal lung-perfusion suddenly developed headache and left facial sensory disturbances. Using computed tomography and magnetic resonance imaging a temporo-parietal brain abscess was diagnosed. After abscess aspiration and antibiotical therapy neurological signs disappeared immediately and the patient could leave hospital without any neurological deficit. Adult patients with congenital cyanotic heart disease are at risk to develop a brain abscess which should therefore be ruled out if headache, fever of unknown origin or focal neurologic signs occur.
