Brain abscess in immunocompetent patients: recent findings.

Curr Opin Infect Dis 2022 06;35(3):238-245

Department of Intensive Care Medicine, AP-HP, Hôpital Bichat - Claude Bernard.

Purpose Of Review: We conducted a systematic review of the literature to update findings on the epidemiology and the management of cerebral abscesses in immunocompetent patients.

Recent Findings: Observational studies suggest that the overall prognosis has improved over the last decades but mortality rates remain high. Several parameters may contribute to a better prognosis, including the identification of common risk factors for brain abscess, the systematic use of brain MRI at diagnosis, the implementation of appropriate neurosurgical and microbiological techniques for diagnosis, the optimization of the antibacterial treatment based on epidemiology and pharmacokinetic/pharmacodynamic studies, and a long-term follow-up for detection of secondary complications.

Can MRI differentiate between ring-enhancing gliomas and intra-axial abscesses?

Vet Radiol Ultrasound 2022 May 4. Epub 2022 May 4.

Diagnostic Imaging Department, Veterinary Hospital "I Portoni Rossi" Anicura Italy, Zola Predosa, Bologna, Italy.

Gliomas of the brain may appear as expansile ring-enhancing masses in MRI studies, mimicking the appearance of intra-axial abscesses. The aims of this study were to compare the MRI features of ring-enhancing gliomas and intra-axial brain abscesses in dogs and cats and to identify the characteristics that might help differentiate them. For this multicenter, retrospective, and observational study, the inclusion criteria were as follows: (a) a definitive diagnosis of glioma or abscess based on cytological or histopathological examination following CSF collection or surgical biopsy/necropsy, respectively; (b) MRI study performed with a high- or low-field MRI scanner, including a same plane T1W pre- and postcontrast, a T2W and a T2 FLAIR sequence in at least one plane.

Pott Puffy Tumor Caused by Dental Infection: A Case Report and Literature Review.

J Craniofac Surg 2022 Mar-Apr 01;33(2):e127-e130

Department of Otorhinolaryngology, Yonsei University Wonju College of Medicine, Wonju, South Korea.

Abstract: Pott puffy tumor (PPT), first described by Sir Percivall Pott in 1760, is a rare clinical entity characterized by a subperiosteal abscess associated with osteomyelitis of the frontal bone caused by direct or hematogenous spread. Although rare in this modern age of antibiotics, this tumor usually occurs as a complication of sinusitis. Moreover, intracranial complications such as subdural abscess, meningitis, sinus thrombosis, or brain abscess can occur concomitantly with the underlying sinusitis, despite the administration of antibiotics.
