(b, c) Thin-section (1-mm collimation) axial CT image (b) and coronal reconstructed CT image (5-mm thickness) (c) obtained on the same day show multifocal ill-defined small areas of nodular opacity (arrows) with the GGO halo sign in both lungs. 3, 1 June 2020 | Radiology: Cardiothoracic Imaging, Vol. (a) Initial chest radiograph shows extensive patchy consolidation (arrows) with air bronchogram (arrowheads) in both lungs, especially in the middle to lower lung zones. One study used CT scans and laboratory tests to compare the clinical features of COVID-19 pneumonia to other types of pneumonia. Respiratory tract infection caused by herpesviridae has been demonstrated after primary infection and reactivation. Pneumonia due to MERS coronavirus in a 27-year-old man who presented with a cough and sputum. In our case (Fig 6), human bocavirus infection manifested as diffuse bilateral patchy consolidation and GGO at chest radiography and patchy consolidation along the bronchovascular bundles with interlobular septal thickening at CT. Direct contact with infected blood also can cause infection (51). For instance, Li and Xia reviewed the chest CT scans of 53 patients [51 with COVID-19 and 2 with adenovirus pneumonia] and found that chest CT abnormalities diagnostic of viral pneumonia were available before a positive laboratory test result in 37 patients [i.e. More than 40 hantavirus species are known, and greater than 20 of these are considered pathogenic in humans. Human coronaviruses are considered as important pathogens that cause infections in pediatric, geriatric, and immunocompromised patients and include upper and lower respiratory tract infections (pneumonia and bronchiolitis) and even acute respiratory distress syndrome (69). Kitazawa T, Yoshihara H, Seo K, Yoshino Y, Ota Y. J Community Hosp Intern Med Perspect. In hematopoietic stem cell transplant recipients, HPIV pneumonia exhibits 50% mortality during early stages and 75% 6-month mortality. The patient underwent reverse-transcription polymerase chain reaction for viral infection with sputum and blood culture and bronchoalveolar lavage to find superimposed infection. Figure 7a. Further studies aimed at elucidating the imaging findings of newly identified viral pathogens, including human bocavirus and coronaviruses, could be of value for proper diagnosis and improvement of clinical outcomes. Pneumonia due to CMV in a 28-year-old man with graft-versus-host disease after bone marrow transplantation for chronic myeloblastic leukemia. CT scans can find many areas of pneumonia not readily detectable by regular X-rays. The test result for hantavirus antibodies was positive, and the titer was increased to 1:512. Does can pneumonia look like a mass in the lungs look the same on a CT scan?? https://www.cdc.gov/nchs/data/nhds/2average/2010ave2_firstlist.pdf, K23 GM110469/GM/NIGMS NIH HHS/United States, R01 AG043471/AG/NIA NIH HHS/United States, U18 IP000299/IP/NCIRD CDC HHS/United States, Kochanek K.D., Murphy S.L., Xu J., Tejada-Vera B. Many types of Bunyaviruses can cause febrile infections, including hemorrhagic fever and encephalitis, in humans (51). (a) Initial chest radiograph shows extensive patchy consolidation (arrows) with air bronchogram (arrowheads) in both lungs, especially in the middle to lower lung zones. This review focuses on the radiographic and computed tomographic patterns of viral pneumonia caused by different pathogens, including new pathogens. (a) Initial chest radiograph shows multiple irregular nodular peribronchial air spaces or GGO (arrows) in both lungs and a small amount of bilateral pleural effusion.
