Radiographics 2021 Mar-Apr;41(2):380-398. Epub 2021 Feb 5.

From the Department of Clinical Radiology, University of Missouri-Columbia, 1 Hospital Dr, Columbia, MO 65212 (J.R.K., A.H.); Department of Radiology, University of Southern California, Los Angeles, Calif (L.F.B.); Departments of Diagnostic Radiology (C.F.) and Pathology (D.S.), Oregon Health Sciences & University, Portland, Ore; and Department of Diagnostic Radiology, University of Kansas Medical Center, Kansas City, Kan (C.M.W.).

The digitization of radiographic studies along with high-speed transmission of images has formed the basis of teleradiology, which has become an integral component in the workflow of a contemporary radiology practice. It is with this advent and growing utilization of teleradiology that the significance of the source location of images has gained importance. Specifically, the importance of where the patient resides and what endemic fungi occur in that location cannot be underestimated. Read More

Endemic Fungi Presenting as Community-Acquired Pneumonia: A Review.

Semin Respir Crit Care Med 2020 Aug 6;41(4):522-537. Epub 2020 Jul 6.

Indiana University, School of Medicine, Pulmonary Critical Care Medicine, Thoracic Transplantation Program, Indianapolis, Indiana.

In endemic areas, dimorphic fungal infections due to , and account for up to 30% of cases of community-acquired pneumonia. Because respiratory manifestations are often indistinguishable from common bacterial causes of pneumonia, the diagnosis of pulmonary histoplasmosis, blastomycosis, and coccidioidomycosis is often delayed and associated with antibiotics overuse. In addition to being highly endemic to certain regions of North America, dimorphic fungi have global significance due to established areas of endemicity in all six inhabited continents, an increasingly interconnected world of travelers and transported goods, and a changing epidemiology as a result of global heating and anthropomorphic land utilization.

Ann Am Thorac Soc 2019 09;16(9):1179-1188

Evidence-Based Practice Center, Mayo Clinic, Rochester, Minnesota.

Prompt diagnosis of invasive fungal infections is important because of the associated morbidity and mortality; however, diagnosis is challenging because of the nonspecific symptoms and radiographic findings. To conduct a systematic review and meta-analysis of studies that evaluated the diagnostic accuracy of serum and bronchoalveolar lavage (BAL) galactomannan (GM) and serum or BAL polymerase chain reaction (PCR) in patients with suspected invasive aspergillosis (IA), β-d-glucan in critically ill patients at risk for candidiasis or candidemia, and serology testing and antigen detection in patients with endemic mycoses (histoplasmosis, blastomycosis, and coccidioidomycosis).

Multimodality Imaging of Focal and Diffuse Fibrosing Mediastinitis.

Radiographics 2019 May-Jun;39(3):651-667. Epub 2019 Apr 5.

From the Department of Radiology, Saint Luke's Hospital of Kansas City, University of Missouri in Kansas City, 4401 Wornall Rd, Kansas City, MO 64111 (S.H.G., J.R.B., M.L.R.d.C., S.M.J., J.J.B.); and Ameripath, Kansas City, Mo (P.M.).

Fibrosing mediastinitis is a rare benign but potentially life-threatening process that occurs because of proliferation of fibrotic tissue in the mediastinum. The focal subtype is more common and typically is associated with an abnormal immunologic response to infection. Affected patients are typically young at presentation, but a wide age range has been reported, without a predilection for either sex. Read More

Endemic pulmonary fungal diseases in immunocompetent patients: an emphasis on thoracic imaging.

Expert Rev Respir Med 2019 03 31;13(3):263-277. Epub 2019 Jan 31.

a Department of Radiology , Universidade Federal do Rio de Janeiro , Rio de Janeiro , Brazil.

Introduction: Systemic endemic mycoses are prevalent in specific geographical areas of the world and are responsible for high rates of morbidity and mortality in these populations, and in immigrants and travelers returning from endemic regions. The most common fungal infections that can affect the lungs of immunocompetent patients include histoplasmosis, coccidioidomycosis, paracoccidioidomycosis, blastomycosis, sporotrichosis, aspergillosis, and cryptococcosis. Diagnosis and management of these diseases remain challenging, especially in non-endemic areas due to the lack of experience. Read More

Tomographic assessment of thoracic fungal diseases: a pattern and signs approach.

Radiol Bras 2018 Sep-Oct;51(5):313-321

Department of Radiology, Universidade Federal do Rio de Janeiro (UFRJ), Rio de Janeiro, RJ, Brazil.

Pulmonary fungal infections, which can be opportunistic or endemic, lead to considerable morbidity and mortality. Such infections have multiple clinical presentations and imaging patterns, overlapping with those of various other diseases, complicating the diagnostic approach. Given the immensity of Brazil, knowledge of the epidemiological context of pulmonary fungal infections in the various regions of the country is paramount when considering their differential diagnoses.

Departamento de Hemato-Patología, Fundación Valle del Lili, Cali, Colombia.

The small lymphocytic lymphoma is a mature B cell neoplasm with a broad spectrum of clinical presentations. Opportunistic infections that are not related to the treatment, even in advanced stages, have a low incidence rate. There are few case reports in the medical literature of patients who have not received immunosuppressive therapy and present with small lymphocytic lymphoma associated with disseminated histoplasmosis at diagnosis.

Detection of (1,3)-β-d-Glucan in Cerebrospinal Fluid in Histoplasma Meningitis.

J Clin Microbiol 2018 10 25;56(10). Epub 2018 Sep 25.

Division of Pulmonary and Critical Care Medicine, Thoracic Transplantation Program, Indiana University-School of Medicine, Indianapolis, Indiana, USA.

The diagnosis of central nervous system (CNS) histoplasmosis is often difficult. Although cerebrospinal fluid (CSF) (1,3)-β-d-glucan (BDG) is available as a biological marker for the diagnosis of fungal meningitis, there are limited data on its use for the diagnosis of meningitis. We evaluated CSF BDG detection, using the Fungitell assay, in patients with CNS histoplasmosis and controls. Read More

Diagnosis and Management of Systemic Endemic Mycoses Causing Pulmonary Disease.

Respiration 2018;96(3):283-301. Epub 2018 Jun 28.

Division of Clinical Infectious Diseases, Research Center Borstel, Borstel, Germany.

Systemic endemic mycoses cause high rates of morbidity and mortality in certain regions of the world and the real impact on global health is not well understood. Diagnosis and management remain challenging, especially in low-prevalence settings, where disease awareness is lacking. The main challenges include the variability of clinical presentation, the fastidious and slow-growing nature of the fungal pathogens, the paucity of diagnostic tests, and the lack of options and toxicity of antifungal drugs.

Tuberculosis and Other Granulomatous Diseases of the Airway.

Thorac Surg Clin 2018 May;28(2):155-161

Laval University, 6364, Chemin Royal, Saint-Laurent-de-l'Île-d'Orléans, Quebec City, Québec G0A3Z0, Canada.

Granulomatous diseases of the airway are challenging lesions to diagnose and effectively manage not only because they are uncommon but also because they can occur in different forms, each with unique clinical and radiological characteristics. Most such lesions can be effectively managed conservatively with repeated airway dilatation, use of intraluminal stents, and specific antimicrobial treatment. The only exception is those lesions presenting with localized airway obstruction wherein surgical resection may be indicated and beneficial. Read More
