Central nervous system infection: imaging findings suggestive of a fungus as the cause.

Radiol Bras 2021 May-Jun;54(3):198-203

Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil.

Fungal infections of the central nervous system (CNS) are rare. However, because of the increase in the number of immunocompromised individuals, they have been gaining prominence in the differential diagnosis of CNS infections. Imaging techniques are sensitive for detecting and localizing an abnormality, in many cases allowing the origin of a lesion to be categorized as infectious, inflammatory, neoplastic, or vascular.

Department of Neurological Sciences, Sri Sathya Sai Institute of Higher Medical Sciences, Bengaluru, Karnataka, India.

 Cardiogenic brain abscess (CBA) is the commonest noncardiac cause of morbidity and mortality in cyanotic heart disease (CHD). The clinical diagnosis of a CBA is often delayed due to its nonspecific presentations and the scarce availability of computed tomography (CT) imaging in resource-restricted settings. We attempted to identify parameters that reliably point to the diagnosis of a CBA in patients with Tetralogy of Fallot (TOF). Read More

Surg Neurol Int 2021 17;12:97. Epub 2021 Mar 17.

Department of Neurology, Papageorgiou Hospital of Thessaloniki, Periferiaki Odos N. Efkarpia, Thessaloniki, Central Macedonia, Greece.

Background: Immunosuppression is a significant parameter in the pathogenesis of brain abscesses (BA) and it could be the result of severe infections such as acquired immunodeficiency syndrome or drug-induced, by several medications used for systemic autoimmune diseases. Leflunomide is a pyrimidine synthesis inhibitor that affects the proliferation of lymphocytes and is used as a disease-modifying antirheumatic drug. Mild infections, particularly those of the respiratory tract and herpes zoster, are one of its most common adverse effects. Read More

[Brain Abscess].

No Shinkei Geka 2021 Mar;49(2):368-374

Department of Radiology, Self-Defence Forces Central Hospital.

Although the prognosis of brain abscesses has historically improved, the mortality rate still ranges from 5 to 32%, with ventricular perforation reaching 50% and 85-100% in fungal brain abscesses. The characteristic finding of ring-like enhancement by contrast-enhanced imaging is non-specific, and DWI, SWI and MR spectroscopy are very useful in differentiating brain abcesses from necrotizing brain tumors. Brain abscesses show apparent diffusion restriction on the DWI/apparent diffusion coefficient(ADC) map, whereas necrotizing brain tumors often show a weak diffusion restriction. Read More

Thalamic abscess in a patient with hereditary hemorrhagic telangiectasia successfully treated with an empiric antibiotic regime: case report and review of the literature.

BMC Infect Dis 2021 Mar 19;21(1):277. Epub 2021 Mar 19.

Department of Infectious Diseases, University Hospital Puerta de Hierro Majadahonda, Madrid, Spain.

Background: Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disease associated with neurological complications, including cerebral abscesses (CA). They tend to be unique, supratentorial and lobar. While the surgical intervention is a rule of thumb when treating and diagnosing the etiology of these lesions, this is not always possible due to dangerous or inaccessible locations. Read More

Diffuse encephalitic toxoplasmosis in HIV.

BMJ Case Rep 2021 Mar 18;14(3). Epub 2021 Mar 18.

Department of Healthcare for Older People, Royal Devon and Exeter NHS Foundation Trust, Exeter, Devon, UK.

This case demonstrates an atypical radiological presentation of cerebral toxoplasmosis in a 62-year-old HIV-positive patient. The diagnosis is discussed alongside MRI imaging, laboratory results and treatment. Central nervous system toxoplasmosis is typically associated with ring enhancing lesions on neuroimaging with contrast, but the radiology for this patient shows diffuse white matter changes and ependymal enhancement, which would normally suggest an alternative diagnosis.

Infectious Diseases and Tropical Medicine Research Center, Isfahan University of Medical Sciences, Isfahan, Iran; Department of Medical Parasitology and Mycology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran. Electronic address:

Aspergillus infection is a well-known complication of severe influenza and severe acute respiratory syndrome coronavirus (SARS-CoV), and these infections have been related with significant morbidity and mortality even when appropriately diagnosed and treated. Recent studies have indicated that SARS-CoV-2 might increase the risk of invasive pulmonary aspergillosis (IPA). Here, we report the first case of Aspergillus ochraceus in a SARS-CoV-2 positive immunocompetent patient, which is complicated by pulmonary and brain infections. Read More

Spontaneous Resolution of Late-Onset, Symptomatic Fluid Collection Localized in the Meningioma Resection Cavity: A Case Report and Suggestion of Possible Pathogenesis.

Brain Sci 2021 Feb 27;11(3). Epub 2021 Feb 27.

Department of Neurosurgery, Chonnam National University Research Institute of Medical Science, Chonnam National University Hwasun Hospital and Medical School, Hwasun 58128, Korea.

Postoperative complications after brain tumor surgery occur occasionally and it is important for clinicians to know how to properly manage each complication. Here, we described a rare case of late-onset, subdural fluid collection localized at the resection cavity that caused motor weakness after convexity meningioma resection, requiring differentiation from an abscess, to help clinicians determine treatment strategies. A 58-year-old right-handed female was admitted to the hospital with a headache and posterior neck pain. Read More

Hyperbaric oxygen for intracranial abscess.

Undersea Hyperb Med 2021 First Quarter;48(1):97-102

Departments of Anesthesiology and Medicine, Center for Hyperbaric Medicine and Environmental Physiology, Duke University, North Carolina U.S.

The term "intracranial abscess" (ICA) includes cerebral abscess, subdural empyema, and epidural empyema, which share many diagnostic and therapeutic similarities and, frequently, very similar etiologies. Infection may occur and spread from a contiguous infection such as sinusitis, otitis, mastoiditis, or dental infection; hematogenous seeding; or cranial trauma. In view of the high morbidity and mortality of ICA and the fact that hyperbaric oxygen therapy (HBO2) is relatively non-invasive and carries a low complication rate, the risk-benefit ratio favors adjunct use of HBO2 therapy in selected patients with intracranial abscess.
