We present a case with brain abscess associated with entrapment of the lateral ventricle appearing more like remarkable brain edema in the temporo-occipital lobe than ventricular dilatation. A 72-year-old man suffering from headache and vomiting visited our clinic. CT and MRI showed brain abscess in the right parieto-occipital lobe, associated with ventriculitis. Lumbar puncture also revealed purulent meningitis. Both symptoms and CSF findings improved after administration of antibiotics. The improved condition continued for two months after admission, but disturbed consciousness and left hemiparesis than appeared. MRI and CT showed entrapment of the lateral ventricle and brain edema of the right temporo-occipital region without ventricular dilatation. Because brain edema was thought to be caused by transudate of the CSF through the ventricular wall, lobectomy of the right temporal lobe and opening of the temporal horn were carried out. Although left hemiparesis and disturbed consciousness and brain edema disappeared after the operation, subdural effusion appeared. Using a subdural-peritoneal shunt, the subdural effusion was prevented and disappeared. In this case, we thought Hounsfield Unit (HU) of the brain edema caused by transudate of CSF through the ventricular wall (12.6) was markedly lower than that of so-called vasogenic edema (25.1) due to active inflammation. Measurement of the HU seemed to be a useful means to differentiate the types of brain edema in this situation from that of vasogenic edema caused by brain abscess, and thus a means for selection of the appropriate treatment.

Multiple brain and liver abscesses developed immediately after Bacillus cereus bacteremia in a neutropenic patient with acute lymphoblastic leukemia. After even 8 weeks of antimicrobial chemotherapy together with administration of granulocyte colony-stimulating factor, every infectious process disappeared but the patient's headache has still persisted. Because the wall of one brain abscess became thin and was in danger of rupturing into the ventricle, surgical drainage was performed, resulting in disappearance of headache and resolution of brain abscess. The present case indicates that a combined medical and surgical approach is mandatory to treat patients with brain abscesses.

The objective of the present study is to describe the diagnosis and treatment of intracranial complications of frontal sinusitis (Pott's puffy tumor) in a series of pediatric patients at our institution. A rare entity, Pott's puffy tumor has been reported in only 21 pediatric cases in the literature of the antibiotic era. The hospital records and radiographic files at Rainbow Babies and Childrens Hospital, Cleveland, Ohio, USA, over the previous 16 years were retrospectively reviewed in a search for patients with the diagnosis of Pott's puffy tumor, defined as scalp swelling and associated intracranial infection. There were 6 male patients and 1 female patient. Ages ranged from 11 to 18 years (median 14.5 years). Intracranial infections consisted of epidural abscess in 5 patients, subdural empyema in 4 and brain abscess in 1. Intraoperative cultures grew anaerobic organisms in 1 patient, microaerophilic streptococcus in 5 patients, Klebsiella species in 1 patient and Streptococcus pneumoniae in another. All patients presented with frontal scalp swelling, and other common symptoms included headache, fever, nasal drainage and frontal sinus tenderness. Five patients were treated with antibiotics prior to their presentation. Four patients presented with neurologic decompensation characterized by varying degrees of hemiparesis, obtundation, pupillary dilatation or aphasia. All patients underwent craniotomy and evacuation of the intracranial infection. Even severely impaired patients demonstrated full neurologic recovery. Despite the widespread use of antibiotics, neurosurgical complications of sinusitis continue to occur. A high degree of suspicion, along with prompt neurosurgical intervention and the use of appropriate antibiotics, can result in favorable outcomes in even the sickest patients.

From October 1988 to March 2001, 5 patients with 6 episodes of intracranial abscesses were admitted to Chiba-Children's Hospital. Average age when they were admitted was 10 years and 1 month. Initial clinical symptoms were fever in 5 cases, and headache in 1 case. It took 21 days from the appearance of the initial symptoms to diagnose the intracranial abscess. Four out of 5 patients had underlying diseases that were prone to cause intracranial abscess. Two patients of these were cyanotic congenital heart diseases (tetralogy of Fallot and asplenic heart), and the other 2 were sinusitis. Computed tomography revealed that brain abscess was found in 5 cases, and subdural empyema in 1 case. There were 3 single and multiple abscesses each. The most common lesion was the temporal lobe. Eight bacterial strains were isolated from 5 cases. Five were streptococci (3 were Streptococcus milleri group, other 2 were Streptococcus oralis and microaerophilic Streptococcus) and 3 were anaerobes (Prevotella loescheii, Prevotella bivia and Fusobacterium nucleatum). Antimicrobial therapy was started with panipenem-betamiprone in 3 cases, imipenem-cilastatin, ceftriaxone, and ampicillin in the other cases resre ctinely. Duration of therapy ranged from 28 to 67 days (45 days, average). In 5 cases, drainage with craniotomy was performed in addition to antimicrobial therapy. One case was treated medically alone, but this was the only case with recurrence after 1 year 2 months. There were no serious complications such as intraventricular rupture of abscess. All patients had good outcomes, but mild neurological sequela was found in 1 case.

We report a case of recurrent cerebellar abscess secondary to middle ear cholesteatoma. A 57-year-old man was admitted to our hospital because of symptoms of headache and nausea in August, 1992. Brain CT scans revealed acute hydrocephalus complicated by a cerebellar abscess. The patient was discharged without any neurological deterioration after systemic antibiotics combined with intrathecal aminoglucoside administration via ventricular drainage. Mannitol was also administrated for 7 days immediately after the patient's admission. The clinical course was uneventful for 8 years afterwards. Follow-up MR images revealed no signs of recurrence. Unfortunately, the patient suffered a recurrence of cerebellar abscess in October, 2000. His condition continued to deteriorate in spite of being treated by systemic antibiototics. MR images and CT scans targeting a portion of his middle ear revealed extensive pus-coated mastoiditis and middle ear cholesteatoma. We thus performed radical mastoidectomy including removal of the middle ear cholesteatoma. After the operation, the cerebellar abscess was ameliorated. He has been free from recurrence for 2 years, so far. Early diagnosis and prompt intervention are necessary for reducing mortality and morbidity rates due to otogenic brain abscess. Recognizing middle ear cholesteatoma as one of the major causes of neurological entities in the cerebellopontine angle portion, accurate otological examination and prompt treatment can possibly bring about a better prognosis.

The patient was 39-year-old male who had been administrated 20 mg of prednisolone for control of chronic eosinophilic pneumonia. He consulted the hospital with fever, headache and gait disturbance. The laboratory data of peripheral blood revealed a smoldering adult T cell leukemia. Computed tomogram of the chest and MRI of the brain revealed a mass in the right middle lobe of the lung and a brain abscess in the left hemisphere respectively. Biopsied specimens from the lung and brain abscess showed an Aspergillus like fungus. In spite of placement of an Ommaya reservoir for administration of AMPH-B and control of intracranial pressure, he died. During the course, specific antigen and specific gene were not detected in the peripheral blood, and no viable organism was isolated from the specimens. Post mortem examination revealed multiple nodular lesions in the lung, parietal pleura, liver, heart and kidney. After autopsy, disseminated aspergillosis was confirmed through a tissue examination using nested PCR for Aspergillus DNA. In this case, we think that viable fungi could endure in the tissue while circulating Aspergillus markers remained undetectable.

A 70-year-old woman with systemic lupus erythematosus presented with a brain abscess manifesting as progressive monoparesis of the right lower extremity over 4 days. She had had no episodes of fever, and did not complain of headache or exhibit any signs of meningeal irritability. Computed tomography of the brain showed a round, low-density mass with strong ring enhancement in the left frontal lobe. Laboratory examination found a moderately elevated serum level of CA19-9, a marker of some digestive organ cancers. Together with the absence of febrile episodes, headache, and a rise in leukocyte count, the initial suspicion was metastatic brain tumor rather than brain abscess. However, diffusion-weighted magnetic resonance imaging depicted the mass as a very hyperintense area. The neuroimaging diagnosis was brain abscess. After conservative treatment with intravenous antibiotics for 6 weeks, the brain abscess completely resolved, and the patient was discharged without neurological deficits.

A 40-year-old man had experienced headaches for 6 days and a 51-year-old man (2 weeks after an operation for perianal abscess) had experienced tingling sensations in the left hand for 10 days. After an epileptic seizure both underwent a CT scan of the brain. On these an abnormality was visible, probably a malignant astrocytoma. After several days of complaint reduction with dexamethasone, drowsiness and leftsided hemiparesis occurred. Emergency operations revealed a brain abscess. In the younger patient drainage and the administration of antibiotics were followed by fatal brain oedema. In the eldest drainage and the administration of antibiotics were followed by the extraction of infected teeth; he recovered with a slight loss of strength in the left hand. Brain abscesses are rare in the Netherlands. The diagnosis can be difficult because clinical signs and symptoms are not specific and because an underlying systemic infection is often not apparent. Diffusion-weighted magnetic resonance imaging can nowadays differentiate purulent brain processes from cystic brain tumors. Early treatment (burr hole aspiration and antibiotics) is usually curative. Nevertheless, mortality continues to be almost 10% and (permanent) morbidity 45%.

Tuberculous brain abscesses in AIDS patients are considered rare with only eight cases reported in the literature. We describe the case of a 34-year-old woman with AIDS and previous toxoplasmic encephalitis who was admitted due to headache and seizures. A brain computed tomography scan disclosed a frontal hypodense lesion with a contrast ring enhancement. Brain abscess was suspected and she underwent a lesion puncture through a trepanation. The material extracted was purulent and the acid-fast smear was markedly positive. Timely medical and surgical approaches allowed a good outcome. Tuberculous abscesses should be considered in the differential diagnosis of focal brain lesions in AIDS patients. Surgical excision or stereotactic aspiration, and antituberculous treatment are the mainstay in the management of these uncommon lesions.

Brucellosis is an infectious disease with multisystem involvement caused by the genus Brucella. Neurological complications including meningitis, meningoencephalitis, myelitis-radiculoneuritis, brain abscess, epidural abscess, and meningovascular syndromes are rarely encountered. We present here a patient with sixth cranial nerve palsy that occurred during treatment for brucellosis, a form of presentation rarely been reported in English-language literature. We conclude that neurobrucellosis, pseudotumor cerebri, and side effects of tetracyclines which are frequently used in brucellosis should be kept in mind when considering intractable headaches and cranial nerve palsies in patients with brucellosis.
