[Brain abscess complicating dental caries in children].

Brain abscess following dental or periapical infection is rare in childhood. This report describes brain abscesses found in two children with dental caries. Case 1.--A 12 year-old boy was admitted because he had suffered from acute meningitis for 3 days. Clinical examination showed symptoms of meningitis plus palsy of the right third and fourth cranial nerves and of the left facial nerve, and a defect in the left temporal field. Funduscopic examination showed papilledema; CT scan and MRI showed a ring-shaped lesion in the right occipital area. The patient was given cefotaxime and thiamphenicol. The abscess was drained; bacteriological examination showed Actinomyces viscosus and Peptostreptococcus magnus. The neurological condition and the CT scan lesion improved, but intracranial pressure increased again on the 17th day after the onset, requiring replacement of the antibiotics by rifampicin and ampicillin plus clavulanic acid for 2 months. This brain abscess appeared to be metastatic, derived from the infection of a large dental cyst due to a dental infection that had been treated 6 months earlier. Case 2.--A 8 1/2 year-old girl was admitted because she was suffering from palsy of the left facial nerve and left arm. She had had headaches and fever for a few days. Clinical examination showed the palsies and drowsiness. CT scan showed two brain abscesses. The patient was given ceftriaxone, fosfocin and metronidazole. She had been treated for a gingival abscess 1 month earlier, and had two infected teeth extracted. Improvement of the intracranial pressure was transient and the antibiotics were changed on the 12th day of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)
