Focal central nervous system infections, as abscess and empyema, due to Salmonella species are unusual. Even more unusual is the association of cerebral abscess, subdural empyema and epidural abscess we report in the present work. This infection appeared in our patient soon after a brain astrocytoma removal and was treated with cefotaxime and gentamicin during three weeks. In spite of documented genus susceptibility to the drugs the infection relapsed in few days. It was definitely cured with ceftazidime alone for six weeks. Third-generation cephalosporins are good alternatives in uncommon infections and specially in central nervous system salmonellosis, as resistances of this genus to classical drugs are lately increasing.
Successful surgery of the sensori-motor region requires precise pre- and intraoperative localization of the sensori-motor region and pyramidal tract. Important aids are the landmarks of cranio-cerebral topography, coronal suture and bregma and the sulcal anatomy of the sensori-motor region, which can be identified in CT or MR images. Due to considerable displacement and distortion of the anatomical structures, elicited by mass lesions, these aids often fail to render reliable support. In this situation, identification of the motor area can be achieved by electrical stimulation of the precentral gyrus in association with the recording of somatosensory evoked potentials of the pre- and postcentral gyrus. The localisation of the "motor mosaics" in relation to the lesion, enable determination of the direction of displacement of the motor strip and the fan of the pyramidal tract. Based on this information the most appropriate route of access to the lesion is selected, either transcortical or transsulcal. Lesion-specific operative techniques as well as location-specific approaches are discussed. With consequent application of these principles the risk of a new persistent motor deficit was as low as 4%. Thus, the indication for surgery in this area can now be set with greater confidence and far more generously than in the past.
A 6-year-old boy esophageal stricture due to the ingestion of caustic 7 months prior to admission. Eight esophageal dilations and a feeding gastrostomy were performed. He presented with seizure, right-sided weakness, fever, and somnolence. Computed tomographic scans revealed multiple brain abscesses. The abscesses were treated by burr-hole drainage. The patient improved and was discharged from the hospital without neurological deficit. Brain abscesses are not very common following esophageal dilation. It should be kept in mind that brain abscess is a potential complication of esophageal dilation.
