Cerebral abscesses imaging: A practical approach

Abstract

Brain abscesses (BAs) are focal infections of the central nervous system (CNS) that start as a localised area of weakening of the brain parenchyma (cerebritis) and develops into a collection of pus surrounded by a capsule. Pyogenic (bacterial) BAs represent the majority of all BAs; in some cases, the diagnostic and therapeutic management can be challenging. Imaging has a primary role in differentiating BAs from other lesions. Conventional magnetic resonance imaging (cMRI) is essential for the identification of the lesion, its localisation and its morphological features. However, cMRI does not allow to reliably Cerebral abscesses imaging: A practical approach

The Effects of NLR on the Diagnosis and Pharmacological Management of Brain Abscesses

“…Some studies have reported that the duration of antibiotic therapy is determined with the help of MRI and DWI results [23]. It has been suggested that, along with the antibiotic regimen, MRI and DWI are helpful tools in the diagnosis of brain abscesses [1,24,25]. In the present study, MRI and DWI were used to diagnosis the brain abscess.…”

“…B rain abscesses are focal infections of the central nervous system that begin in a localized area of the brain parenchyma and gradually develop into an intra-axial collection of encapsulated pus [1]. Brain abscesses can occur through direct extension, where the infection spreads from a nearby area, or via hematogenous dissemination, where the causative pathogen spreads from distant organs to the cerebral tissue.…”

“…The most common symptoms are headache (69%), fever (45%), and nausea and vomiting (40%), respectively [2,4]. Diagnosis and therapeutic management can sometimes be difficult even in patients with neurological findings [1]. Radiological imaging methods play a primary role in the differential diagnosis of brain abscesses from other intracranial pathologies [1].…”

“…Diagnosis and therapeutic management can sometimes be difficult even in patients with neurological findings [1]. Radiological imaging methods play a primary role in the differential diagnosis of brain abscesses from other intracranial pathologies [1]. The conventional magnetic resonance imaging (MRI) method is an indispensable tool for the identification of lesions and their localization and morphological features, but conventional MRI cannot credibly distinguish brain abscesses from other intracranial mass lesions, such as necrotic tumors [1].…”

Diffusion-weighted imaging in the early diagnosis of intraventricular rupture of a brain abscess

“…Brain abscess is a focal infection that begins as a localized area of cerebritis and develops into a mass-like lesion within a circumscribed capsule [1] . A brain abscess can result from an accumulation of infected material as a direct extension of infection originating from other areas (such as ear infections, sinusitis and dental abscesses) or from hematogenous spread in cases of bacterial endocarditis, drug abuse or septic embolic pneumonia.…”
