A retrospective evaluation was performed on 28 cases of paediatric brain abscess (male: female ratio 2.5:1; mean age 9.4 years; range 2.8-16 years) diagnosed between 1967 and 1987. In 46%, congenital cyanotic
heart disease
was identified as a predisposing factor, likewise sinusitis, otitis media or
mastoiditis
in 29% and immunodeficiency in 11%. Pathogenesis remained unclear in 14%. Initial symptoms and signs were predominantly nonspecific; loss of consciousness occurred in 32% of cases, neurological deficit and seizures each in 25%. Since the availability of CT, both diagnostic delay after hospital admission and mortality were substantially reduced: mean delay from 8.4 to 3.0 days, and mortality from 23% to 0%. Seventeen patients (61%) had follow up examinations 9.6 years (mean) after the acute illness (range 1-21 years). Neurological sequelae were diagnosed in 35% of cases, epilepsy in 29%, epileptic potentials during EEG in 12%, and CNS scars in 50%. Psychological testing revealed no statistically significant differences compared to normal populations. CNS scars, and epilepsy and/or epileptic potentials were more common after excision (7 patients) when compared to patients treated by aspiration and/or antibiotics alone (21 patients). It is concluded that excision of brain abscess should be avoided whenever possible. Therapy of choice consists of the administration of adequate antibiotics with or without CT-guided needle aspirations.

Brain abscesses in the young are rare. Only 14 such abscesses have been seen at Texas Children's Hospital since 1968. Most abscesses developed in association with congenital
heart disease
(5), although sinusitis and
mastoiditis
were precipitating causes in two patients and one patient, respectively. The latter three patients' cases are reviewed in detail. Clinical and bacteriologic findings in all patients are discussed. There were signs of increased intracranial pressure in nine patients (64%). All abscesses were drained; in several, repeated drainage was necessary. Anaerobic organisms were recovered in six patients (43%), aerobic organisms were recovered in five (36%), and both were recovered in two (14%). In one patient no growth was reported. Antimicrobial therapy was administered to all patients but one, whose abscess was completely excised. Morbidity and mortality remained significant: three patients (21%) died and one has a residual hemiparesis.

Brain abscess is a serious, life-threatening infection. The infection can originate from contiguous sites of existing infections, such as chronic otitis media, dental infection,
mastoiditis
, or sinusitis, where anaerobic bacteria predominate. The infection can also occur in children with cyanotic congenital
heart disease
, in whom the predominant organisms are viridans, microaerophilic, or anaerobic streptococci, or after head trauma, in which case Staphylococcus aureus, viridans cocci, and Streptococcus pneumoniae are the most prevalent isolates. Enterobacteriaceae, Pseudomonas aeruginosa, yeast, fungi, and mycobacteria are prevalent in the immunocompromised. Radioisotope brain scans, computed tomography, and magnetic resonance imaging are important tools that enable accurate diagnosis of the infection. Proper selection of antimicrobial with good intracranial penetration is essential in the management of intracranial infection. Delay in surgical drainage can be associated with high mortality or morbidity. However, brain abscess, especially in the early phase of cerebritis, may respond to antimicrobial therapy without surgical drainage.

Brain abscess is a relatively uncommon but life-threatening infection in children. It can originate from contiguous site infections (eg, chronic otitis media,
mastoiditis
, sinusitis, meningitis), from distant pathologic states (eg, cyanotic congenital
heart disease
, chronic lung infections), after head trauma or neurosurgical procedures, or from cryptogenic sources. Predominant etiologic microorganisms vary depending on these predisposing factors. Computed tomography and magnetic resonance imaging are essential tools that enable the physician to make an accurate diagnosis of intracranial purulent collections. Proper selection of antimicrobial agents with good penetration of the central nervous system and with adequate coverage of both anaerobic and aerobic bacteria is critical for the medical management of brain abscess. Delay in surgical drainage can be associated with high morbidity and case-fatality rates. In the early phase of cerebritis, however, infection can respond to antibiotic therapy alone. Advances in diagnostic and therapeutic modalities during the last decade have improved the prognosis of this serious disease.
