An infant with a history of atopic dermatitis presented to the emergency department on 5 occasions with flulike symptoms. Eventually, this child presented with signs of infection and increased intracranial pressure: fever, bulging anterior fontanel, and leukocytosis. A computed tomography scan identified a large frontal lobe brain abscess. The abscess was surgically drained; culture was positive for Staphylococcus aureus. The initial source of the infected brain abscess was explored. Ultimately, it was thought to be secondary to impetiginized atopic dermatitis, an unusual but serious consequence of a common skin condition...

A 54-year-old man presented with two episodes of dysarthria and left facial droop. Both episodes resolved by the time of examination. MRI of the brain revealed a right frontotemporal, heterogeneously enhancing mass with surrounding vasogenic oedema, suggestive of a high-grade primary brain neoplasm. The patient was administered preoperative 5-aminolevulinic acid hydrochloride (Gliolan), and fluorescence-guided resection of the lesion was undertaken. Cryptococcus gattii infection was diagnosed from the specimen and the patient was given appropriate antifungal treatment...

Background.: Methanogens are antibiotic-resistant anaerobic archaea which escape routine detection in clinical microbiology. We hypothesized that methanogens may participate as part of the anaerobic community causing brain abscess. Methods.: Methanogens were investigated in one index sample by specific PCR-sequencing and culture. The pathogenesis of a methanogen isolate was assessed in a mouse model of brain abscess. Archaea-specific qPCR and metagenomics were used to detect specific archaeal sequences in brain abscess samples and controls...

Calcifying pseudoneoplasms of the neuraxis (CAPNONs) are extremely rare tumors that are frequently misdiagnosed and overlooked by clinicians. To date, only 40 intracranial lesions have been reported, and in all instances, they were found as a solitary calcified mass. To our knowledge, the current case report is the first to illustrate the development of multiple intraaxial CAPNONs and shed more light on the origin of these lesions. We discuss the case of a 67-year-old woman who presented with a six-year history of recurrent seizures...

REVIEW
Orrett E Ogle
The pathogenesis of odontogenic infection is polymicrobial, consisting of various facultative and strict anaerobes. The dominant isolates are strictly anaerobic gram-negative rods and gram-positive cocci. The periapical infection is the most common form of odontogenic infection. Although odontogenic infections are usually confined to the alveolar ridge vicinity, they can spread into deep fascial spaces. Cavernous sinus thrombosis, brain abscess, airway obstruction, and mediastinitis are possible complications of dental infections...

INTRODUCTION: Odontogenic foci can rarely cause intracranial infection. Hematogenous spread is considered to be the most important pathophysiological mechanism of intracranial infection of odontogenic origin. To investigate the oral origin of intracranial infections, oral surgeons should understand the underlying mechanisms by which oral bacteria spread to the central nervous system. However, there have been very few reports of intracranial infection resulting from odontogenic infection...

Neonatal bacterial meningitis is a common manifestation of late onset neonatal sepsis. Cranial sonography (CRS) has a crucial role in assessment of infants with clinical suspicion of bacterial meningitis as well as follows up of its complications. CRS is performed with high frequency transducer through anterior fontanelle in both coronal and sagittal planes. Various sonographic findings range from echogenic and widened sulci, ventriculomegaly, ventriculitis, hydrocephalus, extra-axial fluid collections, cerebritis and brain abscess...

PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated...
