A 14-year-old adolescent boy experienced a nonsevere infection of the upper respiratory tract. After 10 days, he developed headache, intermittent vomiting, and fever. A sudden prominent swelling of the forehead occurred, and his general condition deteriorated. Cranial computed tomography showed a subdural empyema and subperiosteal abscess owing to osteomyelitis of the frontal bone. Surgical drainage of the subdural empyema and the subperiosteal abscess was performed, and appropriate long-term antibiotic therapy was initiated. The swelling of the forehead caused by a subperiosteal abscess with osteomyelitis of the frontal bone after frontal sinusitis or trauma is known as Pott's puffy tumor. This case demonstrates that swelling of the forehead in the presence of upper respiratory tract infection should lead to prompt evaluation for complications.

Little is known regarding typical neuropsychological outcomes of intracranial empyema, a rare complication of sinusitis marked by accumulation of purulent material adjacent to the brain. A 15-year-old, right-handed male presented with a 3-day history of congestion, lethargy, fever, headache, dizziness, unequal pupil dilation, and right-sided facial droop. Computed tomography revealed right-sided subdural empyema causing subfalcine, central, foraminal uncal, and tonsillar herniation. Postoperative inpatient neuropsychological consultation was requested 17 days postsurgery due to language deficits. Through comparison of neuropsychological and radiological findings, this case of subdural empyema demonstrates the anatomical and functional impact of mass effect on the brainstem and the vasculature of the contralateral hemisphere. Deficits were observed in expressive language, processing speed, and fine motor functioning, all of which lingered 6 months postacute. This case study reviews the pathophysiology of subdural empyema and illustrates its potential neuropsychological impact to inform clinicians encountering this rare condition.

BACKGROUND: Non traumatic intracranial infections are a well recognized disease process encountered in neurosurgery and otolaryngology practices. In this case series study, we analyze the patients that presented with this condition to the neurosurgical unit of the University Teaching Hospital in Lusaka, Zambia. METHODS: This is a prospective analysis of a case series of patients that were treated for non traumatic intracranial infections. The analysis involved the following parameters: age, sex, clinical presentation, HIV serostatus, CT/neurosurgical findings, microbiology, and treatment outcome. This was done over a 3-year period. RESULTS: Eighteen patients were treated for non traumatic intracranial infections, of which 12 were male and 6 were female. The youngest patient was 9 and the oldest was 70, with a mean age of 25.33 years. Headache and fever were the most common clinical presentation, followed by sinusitis. Six patients were HIV-positive and 5 were already on HAART prior to presentation. Intracerebral abscesses, both solitary and multiple, were seen in 10 patients, while epidural and subdural empyema were present in 2 patients each. In one patient, localized encephalitis was seen, and the other 3 patients had a mixture of intracerebral abscess and subdural empyema. Gram-positive cocci comprising streptococci and staphylococci were isolated in 10 cases, while negative cultures were seen in 4 and actinomycete was seen in 1 patient. Fourteen patients had a good outcome, while 4 patients died, including 3 with a positive HIV serostatus. Two of these HIV-positive patients had very low CD4 counts. CONCLUSION: The pattern for non traumatic intracranial infections seen at the University Teaching Hospital in Lusaka is not different from other published series. However, the role of HIV in the treatment outcome needs further study.

Salmonella focal intracranial infections are reported rarely. They tend to occur in immunocompromised patients. We present here a case of Salmonella typhimurium epidural empyema, with osteomyelitis of the adjacent frontal bone, in a 37-year-old human immunodeficiency virus positive man who presented with a three-day history of headache, fever, and sweats. He was treated successfully with antibiotics and surgical drainage.

Headache caused by subdural empyema is usually associated with fever and symptoms and/or clinical signs of meningeal irritation and increased intracranial pressure. We describe a patient with headache with absence of these signs or symptoms of meningeal irritation or intracranial pressure, who turned out to have a parafalcine subduralempyema. A 28-year-old man had headache for 2 weeks, which had started with visual symptoms with duration of 5 minutes. Two days later, he developed fever. During these 2 weeks, he had recurrence of visual symptoms for 4 times, with duration of several minutes.Neurologic examination at presentation on the emergency department showed no meningeal irritation or papilledema. However, on closer examination, a limited homonymous hemianopsia on the left side and a drift of the left leg were found. Magnetic resonance imaging showed parafalcine subdural empyema on the right side of the falx and a small brain abscess right occipitally. Neuronavigated craniotomy was performed, which confirmed the presence of empyema and allowed culture of the specimens. Streptococcus milleri group was cultured,which allowed narrowing of the antibiotic therapy to Benzylpenicillin12 million entities per 24 hours. Headache and subdural empyema diminished during treatment, and at follow-up 12 weeks after start of treatment, patient had no remaining complaints. Parafalcine-located subdural empyema can present without presence of clear localizing symptoms or signs like meningeal irritation and increased intracranial pressure. When headache is accompanied with fever, one should extensively question neurologic symptoms, and a thorough neurologic examination should be done.

We describe the rare occurrence of an Actinomyces meyeri cerebral abscess in a 55-year-old woman following a dental extraction. This patient presented with a 2-day history of hemisensory loss, hyper-reflexia and retro-orbital headache, 7 days following a dental extraction for apical peridonitis. Neuroimaging showed a large left parietal abscess with surrounding empyema. The patient underwent craniotomy and drainage of the abscess. A. meyeri was cultured. Actinomycosis is a rare cause of cerebral abscess. The A. meyeri subtype is particularly rare, accounting for less than 1% of specimens. This case describes an unusually brief course of the disease, which is usually insidious. Parietal lobe involvement is unusual as cerebral abscesses usually have a predilection for the frontal and temporal regions of the brain. Although there are no randomised trials to guide therapy, current consensus is to use a prolonged course of intravenous antibiotics, followed by 6-12 months of oral therapy.

Intracranial infections in children are a relatively rare, but potentially severe condition. Because of the potential for rapid deterioration, timely diagnosis and treatment are necessary. These infections are categorized based on their intracranial location: epidural abscess, subdural empyema, and brain abscess. They largely arise from direct extension of adjacent infection, hematogenous seeding, or trauma. Clinical presentations of intracranial infections also vary. However, common signs and symptoms include headache, fever, nausea and vomiting, altered mental status, focal neurologic deficits, and seizures. In general, MRI demonstrates a peripherally enhancing lesion with high signal on diffusion weighted imaging (DWI). Bacterial isolates vary, but most commonly are a single pathogen. Successful treatment requires a multidisciplinary team approach including such modalities as antibiotic therapy and surgical drainage. When possible, open surgical evacuation of the abscess is preferred, however, in cases of deep-seated lesions, or in unstable patients, aspiration has also been performed with good results.

Subdural empyema related to Streptococcus constellatus is extremely rare in an immunocompetent child, and also there is no reported case along with Staphylococcus lugdunensis infection. Although Streptococcus constellatus has been determined as a co-pathogen with anerobic bacteria in many infections, it has not been reported in combination with Staphylococcus lugdunensis. The authors describe a case of previously healthy 16-y-old child with unilateral subdural empyema due to these bacteria. Sinusitis was the only predisposing factor in the index case. The authors propose that some cases of culture-negative intracranial infections may be due to these infectious agents. Therefore, these agents should be considered as causes of intracranial infection in persistent complaints such as fever and headache after sinusitis in children. It is important to treat them with effective antibiotics and early surgical intervention for favorable outcome, because fatal cases were reported due to Streptococcus constellatus infections.

A 69-year-old man developed motor aphasia and right hemiparesis with severe headache, during the treatment of cellulitis and sepsis due to cat bites. Brain CT showed a low density, crescent-shaped lesion in the left subdural space, which was hypointense on brain diffusion-weighted imaging (DWI). One week later, when his neurological symptoms had worsened, the signal of the subdural lesion had changed to hyperintense on DWI. The lesion was capsule-shaped when enhanced by Gadolinium. The signal changes on DWI of the lesion indicated the existing hematoma had changed to an empyema, or so-called infected subdural hematoma, due to a hematogenous bacterial infection. Pasteurella multocida, a resident microbe in the oral cavity of cats, could be the responsible pathogen in this case. The patient recovered completely after treatment with intravenous high dose antibiotics. This is an important case report describing the transformation from a chronic subdural hematoma into a subdural empyema by DWI.

The prompt identification of sepsis in children is challenging, but once sepsis is identified, initiation of care and determination of proper disposition may be insufficient to ensure optimal outcomes. The best opportunity for full recovery also requires rapid identification and treatment of the infectious source. Acute bacterial sinusitis is common in the pediatric population, and although intracranial complications of sinusitis are rare, they are associated with significant morbidity and mortality. History and physical examination may be imperfectly sensitive for the presence of acute bacterial sinusitis and its intracranial complications. We present a case of pediatric sepsis in which the diagnosis of intracranial extension of bacterial sinusitis was not made during the first phase of care and describe complications that followed. Emergency physicians should consider subdural empyema in patients presenting with fever, nausea and headache with worrisome vital signs and laboratory values suggestive of a severe infection.
