295, No. (a) Initial chest radiograph shows multinodular airspace opacity (arrows) in the right lung. 4, 13 February 2020 | Radiology, Vol. In hematopoietic stem cell transplant recipients, HPIV pneumonia exhibits 50% mortality during early stages and 75% 6-month mortality. No differences have been observed between the CT findings of immunocompromised and immunocompetent patients (9). *Specimens for diagnostic test were respiratory samples (nasopharyngeal swab or aspirate, sputum, tracheal aspirate, or bronchoalveolar lavage fluid), unless otherwise stated. These pulmonary findings are occasionally secondary to renal failure (59). The presence of mononuclear or multinuclear epithelial cells containing an intranuclear inclusion suggests the diagnosis of HSV pneumonia. Figure 11a. The lesions may calcify, and well-defined scattered 2–3-mm hyperattenuating calcifications can persist (25). (e) Pneumonia due to rhinovirus shows multiple ill-defined patchy areas of GGO (arrows) with interlobular septal thickening (arrowheads) in both lungs.  |  Pneumonia caused by the new coronavirus can show up as distinctive hazy patches on the outer edges of … (a) Pneumonia due to varicella-zoster virus shows multifocal 1–10-mm well-defined or ill-defined nodular opacity (arrows) with a surrounding halo or patchy GGO (arrowheads) in both lungs. A CT scan shows detailed cross-sectional images of your lungs and hence, it can detect lung cancer more accurately than chest X-ray. Figure 8c. A number of pathogens can cause pneumonia, including viruses, bacteria, fungi and parasites. (b, c) Axial CT images obtained on the same day at the lower trachea level (b) and both lower lobe basal segments (c) show irregular areas of increased opacity with interlobular septal thickening (arrowheads) and ill-defined patchy GGO (arrows) in both lungs. In terms of COVID-19, Dr. Cortopassi explains GGOs on a CT scan are indicative of COVID-19-related pneumonia, or lung inflammation caused by the viral infection. About half got CT scans and half got standard chest X … Percentage of the area of lung involvement: + = 10%–25%, ++ = 25%–50%, +++ = 50%–75, ++++ = greater than 75%. CT scans can find many areas of pneumonia not readily detectable by regular X-rays. Several antiviral drugs are currently available (Table 3). Antiviral therapy can reduce attack rates and decrease outbreaks and could reduce the public health burden. A recent prospective study (47) showed that RSV was the most common viral pathogen (28%) in children hospitalized for community-acquired pneumonia in the United States. (b, c) Axial chest CT images (5-mm thickness) obtained on the same day at the interlobar bronchi level (b) and the inferior pulmonary vein level (c) show ill-defined patchy GGO (arrowheads) and lobar consolidations (arrows). Figure 8a. Pneumonia due to RSV in a 58-year-old woman with acute myeloid leukemia who presented with fever. Pneumonia due to CMV in a 28-year-old man with graft-versus-host disease after bone marrow transplantation for chronic myeloblastic leukemia. There are a number of severe pathogenic human herpesviruses including HSV types 1 and 2, varicella-zoster virus, Epstein-Barr virus, CMV, and herpesviruses 6 and 7. Figure 1e. Figure 12c. -.
