[Brain abscess (Part 5)--Brain abscess following internal carotid occlusion (author's transl)].

Three cases of brain abscess following an occlusion of the internal carotid artery were reported. Case 1: A 6-year-old girl with congenital heart disease was admitted with headache, disturbance of consciousness and left hemiparesis. Right carotid angiography revealed an occlusion of the right internal carotid artery. After 6 months, she was readmitted with high fever. CT scan revealed a low density area and a ring-like shadow at the same site of cerebral infarction. Case 2: A 69-year-old man was admitted in semicoma and with right hemiplegia. Left angiography revealed an occlusion of the left internal carotid artery. After 2 months, a brain abscess was noted in the infarcted area. Case 3: A 20-year-old man with congenital heart disease, was admitted due to headache, vomiting and high fever. CT scan revealed a brain abscess in the right frontal lobe. Carotid angiography showed bilateral internal carotid artery occlusion. We concluded that diminution of cerebral oxygen and encephalomalacia are predisposing factors to the evolution of brain abscess.

Relevance of antibiotics in the treatment of brain abscesses. Report of a case with eight simultaneous brain abscesses treated and cured medically.

A case of eight simultaneous brain abscesses in the right cerebral hemisphere, treated medically after puncture of two of them, is reported. Antibiotics and hypertonic mannitol and, after seven days, dexamethasone were sufficient to cure these lesions. CT scan was of primary importance to follow the evolution under treatment. To get the best efficiency from antibiotics, identification of the microorganism and assessment of its resistance to antibiotics are necessary. It is suggested that in certain conditions medical therapy might be sufficient to treat cerebral abscess, after simple puncture to isolate the infecting agent. Corticosteroids should be avoided in the acute phase because they prevent antibiotics from penetrating the abscesses.

Listeria monocytogenes: brain abscess or meningoencephalitis?

A brain abscess caused by Listeria monocytogenes developed in an immunosuppressed renal transplant patient. Meningitis and meningoencephalitis from this organism were encountered in three other renal transplant recipients at this medical center during the past 4 years. Focal neurologic deficits occurred in patients with either Listeria abscess or meningoencephalitis. Computerized tomography was a rapid aid to the diagnosis of abscess. Immunosuppression has increased the incidence of central nervous system Listeria infections, but ampicillin still provides effective treatment, even when immunosuppressive therapy is continued. Limited experience with Listeria brain abscess suggests that surgical intervention improves the prognosis.

Brain abscess and cystic fibrosis.

Brain abscess has only recently been considered a complication of cystic fibrosis. Three patients are reported here and a fourth cited from the literature. All of our patients were young adults with advanced pulmonary disease. The bacteria involved were mouth organisms and were found in the sputum culture in only one of the patients. Resistance was present to previously given antibiotics. As patients with cystic fibrosis survive into adulthood, the risk of developing a brain abscess appears to increase.

Use of computerized tomography in nonsurgical management of brain abscess.

Two patients with hematogenous brain abscesses demonstrated by computerized tomographic (CT) scans were successfully treated without surgical intervention. The first patient had congenital cyanotic heart disease and multiple brain abscesses complicated by presumed rupture into the ventricles. By the time these clinical diagnoses were established, she had shown substantial improvement after antibiotic therapy alone. The second patient with bronchiectasis had a single abscess in the dominant hemisphere. Medical management was successful. Subsequent CT scans in both patients provided reassurance that clinical improvement was accompanied by anatomical healing. The use of noninvasive diagnostic techniques should encourage the formulation of new criteria for the management of cerebral abscess in carefully evaluated and closely observed patients.

Electroencephalographic cranial computerized tomographic correlations in brain abscess.

The authors studied 19 cases of brain abscess. The investigation included one or more EEG records from 13 patients and one or more cranial computerized tomograms in all cases. In this work the two techniques were associated to establish the diagnosis of cerebral abscess. The EEG is almost always abnormal and pronounced EEG disturbances are, in most cases, sufficient for indicating a diagnosis of a space-occupying process. On the other hand, EEG patterns suggestive of brain abscess were detected in only 38% of the patients. In brain abscess, CCT is of considerable value since the existence of 'suppurative' images was demonstrated in all cases and of these, 70% were characteristic. The association of these two techniques is thus extremely useful in the diagnosis of cerebral abscess, to follow its evolution and to detect postoperative relapse or to evaluate the efficiency of medical management alone.

Production of experimental brain abscess in the rat.

Experimental evaluation of brain abscess has been inhibited by the lack of a simple and reproducible model in small animals. A stereotaxic headholder and slow infusion of 1 microliter of saline, containing a known number of bacteria, were used to produce brain abscess consistently in the rat. The natural history of the brain abscess produced by this technique closely simulated that found in the human clinical situation.

Epilepsy and brain abscess.

Among 22 children who had recovered from brain abscess, 9 later developed epilepsy. Epilepsy developing as a consequence of brain abscess depends on the length of the catamnestic period and the localization of the abscess. The appearance of epilepsy is more frequent after frontal and temporal abscesses and in cases presenting symptoms in the acute phase of the abscess. Since epilepsy may develop years or even decades after recovery from the brain abscess, it is recommended to keep the patient under control for years.

Proteus mirabilis brain abscess in a neonate.

Occasionally a brain abscess has been observed in a neonate. This report presents a unique case of a septic infant who developed a proteus mirabilis brain abscess shortly after birth, which persisted undetected until 21/2 months of age.

[CT findings in brain abscesses (author's transl)].

Seventeen patients with brain abscesses are reported, some with multiple lesions. The computer tomographic criteria for the diagnosis with and without enhancement are described. The advantages of computer tomography compared with other neuroradiological methods for the diagnosis and follow-up of abscesses is stressed. Good therapeutic results have been obtained from simple puncture of the lesion.

Brain abscess following the insertion of skull tongs.

Brain abscess is an uncommon complication of the insertion of skull tongs. The two cases reported demonstrate the difficulty that may occur in diagnosis and the high mortality associated with this complication.

Experimental brain abscess evolution: computed tomographic and neuropathologic correlation.

Brain abscess evolution was studied in dogs by correlating the CT appearance with the neuropathologic findings. The abscess, produced by direct inoculation, progressed from an area of cerebritis to a well encapsulated abscess over 14 days. Ring enhancement was seen in the cerebritis stage prior to capsule formation. The ring reached its maximum size at this stage and correlated best with the area of cerebritis surrounding the developing necrotic center; the rim of this ring increased in thickness, resulting in progressive diminution of the central lucent area on scans delayed up to 60 min. The diameter of the ring decreased as cerebritis receded. Once the capsule had formed, the central lucent area was similar and no longer filled in on delayed scans.

[Differential-diagnostic problems with the brain abscess in axial computerized tomography (author's transl)].

On the base of three autoptically controlled cases with ring-shaped findings in the CT the problem of the differential diagnosis of the brain abscess in axial computerized tomography is discussed. A brain abscess must especially be taken into account when the hyperdense anulus already occurs without enhancement by contrast media. The ring-shaped finding is then caused by the high amount of collagen fibres within the abscess membrane, which has no comparable correlate in other focal processes of the brain.

Assessment of the postoperative course of excised brain abscess by computerized tomography.

We present two patients with brain abscess who underwent complete excision with a satisfactory clinical outcome although serial computerized tomography (CT) Scans in the early postoperative period seemed to indicate a large residual abscess in each case. We recommend treatment based on the clinical course rather than the CT scan appearance, indicate that earlier reports on this topic may be misleading, and suggest an explanation for these findings.
