In medical school radiology they said, “ The lung is stupid. 2019;97(6):508-517. doi: 10.1159/000495068. Epub 2019 Jan 9. Pleural effusion is common (16). Patients with comorbidities such as diabetes or chronic hepatitis exhibited increased mortality. Schemas show typical CT patterns of viral pneumonia. (a) Initial chest radiograph shows multinodular airspace opacity (arrows) in the right lung. Similarly, cytomegalovirus (CMV) exhibits acute interstitial pneumonia with diffuse alveolar edema with fibrinous exudate. Pathogens such as Haemophilus influenzae, Staphylococcus aureus, and gram-negative enteric bacteria cause clinical syndromes similar to that caused by Streptococcus pneumoniae. (b, c) Axial thin-section (1-mm collimation) chest CT images obtained on the same day show irregular patchy consolidation (arrows) along the bronchovascular bundles and in peripheral areas of the lungs, bronchial wall thickening, and interlobular septal thickening (arrowhead), with a small amount of bilateral pleural effusion (*). Clipboard, Search History, and several other advanced features are temporarily unavailable. The animal hosts of SARS coronavirus appear to include the masked palm civet, raccoon dogs, and the Chinese ferret-badger (73). USA.gov. Rates of emergency department visits due to pneumonia in the United States, July 2006-June 2009. The radiologic features of SARS are similar to those of other community-acquired types of pneumonia. It is usually grouped under atypical pneumonia. (b, c) Axial thin-section (1-mm collimation) CT images obtained on the same day, at the lower trachea level (b) and interlobar area level (c), show ill-defined GGO nodules, interlobular septal thickening (arrowheads), and diffuse GGO (arrows) in both lungs, with a scanty amount of bilateral pleural effusion (* in c). Chest radiograph obtained 1 day after presentation, when the patient suddenly progressed to having decreased blood pressure, shows pulmonary edema and bilateral pleural effusion (*). Splenomegaly is common. 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. Hilar lymphadenopathy and pleural effusion are commonly associated with measles (27). However, in individuals with chronic diseases, the elderly, and infants, severe complications from influenza A viruses, including hemorrhagic bronchitis or fulminant pneumonia (primary viral or secondary bacterial), may occur. No differences have been observed between the CT findings of immunocompromised and immunocompetent patients (9). Enter your email address below and we will send you the reset instructions. In most patients, peripheral lung involvement is common. A small amount of bilateral pleural effusion (*) is noted. Figure 12d. Yes, They can look alike on CT scan. 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. 295, No. Initial chest radiographs are normal but soon progress to show multifocal airspace consolidation, predominantly in the lower lung zone. Figure 7c. CT Scan Produces Twice as Many False Alarms as X-rays The new study involved more than 3,000 current or former smokers aged 55 to 74. NIH These mononuclear cells are also present in the alveolar exudates (32). More than 40 hantavirus species are known, and greater than 20 of these are considered pathogenic in humans. NLM What does a coronavirus infection look like in the lungs? Scattered small calcifications of varying sizes (1–10 mm) can be seen (24). Infectious Diseases Society of America/American Thoracic Society consensus guidelines on the management of community-acquired pneumonia in adults. Adenovirus infection exhibits more severe and fatal conditions with acute respiratory distress syndrome in immunocompromised patients. Although the CT scan cannot give a definitive diagnosis, it is helpful in the evaluation of lung diseases and conditions such as pneumonia RSV infection was noted to be common in adults who require admission to an intensive care unit from November to February (40). Patients admitted to hospital with suspected pneumonia and normal chest radiographs: epidemiology, microbiology, and outcomes. Legionella pneumonia, also known as Legionnaires' disease, refers to pulmonary infection primarily with the organism Legionella pneumophila. Does can pneumonia look like a mass in the lungs look the same on a CT scan?? (b) Pneumonia due to CMV shows diffuse ill-defined patchy GGO with interlobular septal thickening (arrowheads) in both lungs. Shown is a CT scan from a 65-year-old man in China with COVID-19. CT patterns of viral pneumonia are related to the pathogenesis of pulmonary viral infection (Table 2). HSV pneumonia is caused predominately by HSV type 1 and rarely by HSV type 2 (16,17). By considering both the clinical and radiologic characteristics, radiologists can suggest the diagnosis of viral pneumonia. (a) Initial chest radiograph shows ill-defined patchy consolidation and GGO (arrows) in the left middle to lower lungs and the right lower lung zone. In the CT scans of his lungs, white patches can clearly be seen. Can Pneumonia Look Like Something Else on an X-ray?. 2, No. In patients with active chickenpox, predisposing factors, and new pulmonary infiltrates with small nodules, the diagnosis of varicella-zoster virus pneumonia should be considered and/or excluded. However, it can cause life-threatening pulmonary infection in immunocompromised patients owing to reactivation of the latent virus or infusion of CMV-seropositive marrow or blood products. Schemas show typical CT patterns of viral pneumonia. (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. Pleural effusion is common. The following pictures show different lung scans from various ACC patients with lung metastases (focal rounded pulmonary opacities also called \"nodules\" or \"lesions\"). However, in problematic cases, varicella-zoster serologic evaluation can be performed to confirm the diagnosis. With the recent advancement in molecular biology and the ability to amplify multiple viral genomes by using multiplex reverse-transcription polymerase chain reaction assays, several new human respiratory viruses, such as human metapneumovirus (HMPV), human coronaviruses, and bocavirus have been discovered (3,4). (a) Chest radiograph shows diffuse irregular patchy consolidation (arrows) and GGO in both lungs. (c) Axial CT image obtained on the same day as b shows irregular consolidation (arrows) along the bronchovascular bundles and diffuse GGO with interlobular septal thickening (arrowheads) in both lungs. Pneumonia due to CMV in a 28-year-old man with graft-versus-host disease after bone marrow transplantation for chronic myeloblastic leukemia. Thickened interlobular septa also are observed. COVID-19 lung patterns show few clues for treating pneumonia Shown is a CT scan from a 65-year-old man in China with COVID-19. (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. The virus belongs to the same family as those that caused the SARS (Severe Acute Respiratory Syndrome) and … Although not all cases manifest with typical patterns, most typical imaging patterns of viral pneumonia can be classified according to viral families. I know this is tiny, too small to biopsy. Diagnostic tests including radiologic studies and blood or serologic tests that could help establish the cause of pneumonia would reduce the use of antibiotics and may improve the clinical course. CT Scan Produces Twice as Many False Alarms as X-rays The new study involved more than 3,000 current or former smokers aged 55 to 74. CT usually shows 1–10-mm well-defined or ill-defined nodules with a surrounding halo of GGO, patchy GGO, and coalescence of nodules diffusely throughout both lungs. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. (c) Pneumonia due to HMPV shows multiple ill-defined nodules (arrows) or GGO (arrowhead) along the bronchovascular bundles in both lungs. This mass will look like a white spot on your lungs, while the lung itself will appear black. Figure 6b. 4, 5 June 2020 | RadioGraphics, Vol. Some reports from China have suggested that, in some patients with COVID-19 pneumonia, abnormalities on chest CT may appear despite negative swab tests. (b, c) Axial thin-section (1-mm collimation) CT images at the carina (b) and the left inferior pulmonary vein level (c) show diffuse interstitial and interlobular septal thickening (arrowheads) with patchy GGO (arrows) in both lungs. HPIV is a single-stranded RNA virus and a member of the family Paramyxoviridae. The disease usually causes a lobar or segmental pattern, and a patchy bronchopneumonic pattern involving the lower lobes is seen in the elderly. Imaging for the Management of Community-Acquired Pneumonia: What to Do if the Chest Radiograph Is Clear. Additionally, the absence of an abnormality on either a chest x-ray or CT scan does not necessarily exclude COVID-19. For example, the use of antiviral therapy for influenza is important in reducing the infection rate and preventing outbreaks (87). The most common radiologic abnormalities are mediastinal lymphadenopathy, and, rarely, interstitial infiltrates and widespread GGO can be seen. Although the CT scan cannot give a definitive diagnosis, it is helpful in the evaluation of lung diseases and conditions such as pneumonia, cancer, blood clots or damage caused by smoking. A chest computed tomography (CT) scan is an imaging test that takes detailed pictures of the lungs and the inside of the chest. This site needs JavaScript to work properly. Figure 9c. Conclusions: However, if he is worried about an atypical infection (walking pneumonia) or other types of lung disease, a CT is better. Most pictures are taken from a CT scan where a contrast agent was used. Figure 2b. Pneumonia is a general term used to describe a lung infection. (a) Initial chest radiograph shows multifocal reticulonodular infiltrations (arrows) in both lungs. Although not all cases demonstrate typical imaging patterns, most viral pneumonia patterns exhibit similarity on the basis of viridae (Fig 1). Figure 1b. Aspiration pneumonia is caused by a direct chemical insult due to the entry of a foreign substance, solid or liquid, into the respiratory tract. Hantavirus cardiopulmonary syndrome characteristically involves the lung and manifests as respiratory distress from noncardiogenic edema. Figure 13b. Figure 12a. ), and Department of Laboratory Medicine (H.S. Like RSV, HMPV is usually associated with acute respiratory tract infections including upper airway disease, lower airway bronchitis and bronchiolitis, influenza-like syndrome, and pneumonia.

September 10, 2018. Human RSV infection leads to bronchiolitis, pneumonia, and asthma in all age groups; infants, young children, and immunocompromised hosts are likely to present with severe respiratory infection (46). These pulmonary findings are occasionally secondary to renal failure (59). However, identification of the underlying viral pathogens may not always be easy. Influenza viruses are members of the Orthomyxoviridae family. The imaging findings of viral pneumonia are diverse and overlap with those of other nonviral infectious and inflammatory conditions. (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). The novel coronavirus SARS-CoV-2 was first made known to the world on December 31, 2019, when the Chinese government apprised the World Health Organization (WHO) of the spreading of respiratory illness that closely resembled viral pneumonia, with fever, cough, and shortness of breath. Pneumonia due to RSV in a 58-year-old woman with acute myeloid leukemia who presented with fever. This infection occurs predominantly (46.7%) from June to September. The most common imaging finding of Avian flu is multifocal consolidation. Results: Adults hospitalized with CAP who had radiological evidence of pneumonia on CT scan but not on concurrent chest radiograph had pathogens, disease severity, and outcomes similar to patients who had signs of pneumonia on chest radiography. Obstructing lesions in the bronchi can be found which would ordinarily be missed by X-ray as can enlarged lymph nodes. Methods: For this journal-based SA-CME activity, the authors, editor, and reviewers have disclosed no relevant relationships. In this article, we’ll take a closer look at COVID-19 pneumonia. Pneumonia due to RSV in a 58-year-old woman with acute myeloid leukemia who presented with fever. *Specimens for diagnostic test were respiratory samples (nasopharyngeal swab or aspirate, sputum, tracheal aspirate, or bronchoalveolar lavage fluid), unless otherwise stated. The virus was named SARS-like coronavirus, novel coronavirus, or human coronavirus Erasmus Medical Center (EMC) when it was first discovered. (a) Initial chest radiograph shows extensive patchy consolidation (arrows) with air bronchogram (arrowheads) in both lungs, especially in the middle to lower lung zones. Although not all cases demonstrate typical imaging patterns, most viral pneumonia patterns exhibit similarity on the basis of viridae ( Fig 1 ). (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. (a) Initial chest radiograph shows poorly defined nodules (arrows) and reticular areas of increased opacity in both lungs. It can show the size, shape, position, and depth of any lung tumor. Lobar pneumonia | Radiology Reference Article | Radiopaedia.org. (a) Initial chest radiograph shows ill-defined diffuse reticular areas of increased opacity (arrows) in both lungs. Pneumonia due to varicella-zoster virus (α Herpesvirinae) in a 53-year-old man who underwent liver transplantation 5 months before contracting the disease. Imaging & other potential predictors of deterioration in COVID-19. (b) Pneumonia due to CMV shows diffuse ill-defined patchy GGO with interlobular septal thickening (arrowheads) in both lungs. Although a definite diagnosis cannot be achieved on the basis of imaging features alone, recognition of viral pneumonia patterns may aid in differentiating viral pathogens, thus reducing the use of antibiotics.
