![]() Radiographic and CT Features of Viral Pneumonia. bronchopneumonia ) or lobar pulmonary opacities (i.e. Measure the persons temperature, pulse rate and blood pressure, respiratory rate, and assess for signs of confusion. Examine the person, paying particular attention to the chest. Bacterial pneumonia characteristically produces focal segmental (i.e. Additional symptoms such as breathlessness, wheeze, pleuritic pain, and fever. There is also a large overlap of imaging features with non-pneumonic processes 3. Hyun Jung Koo, Soyeoun Lim, Jooae Choe et-al. Chest x-ray and CT are unable to differentiate bacterial pneumonia from non-bacterial pneumonia 6. Viral pneumonias in adults: radiologic and pathologic findings. The CT appearance of lower respiratory infection due to parainfluenza virus in adults. Chest computed tomographic imaging characteristics of viral acute lower respiratory tract illnesses: a case-control study. CT of viral lower respiratory tract infections in adults: comparison among viral organisms and between viral and bacterial infections. Clinical and radiological features of respiratory syncytial virus in solid organ transplant recipients: a single-center experience. Ariza-Heredia EJ, Fishman JE, Cleary T et-al. High-resolution CT findings of respiratory syncytial virus pneumonia after bone marrow transplantation. Gasparetto EL, Escuissato DL, Marchiori E et-al. Imaging findings alone are not specific enough for the definitive diagnosis of viral pneumonia and radiographic patterns can be variable, depending on the specific viral strain, as well as host factors. Pleural effusion, hilar lymphadenopathy and pneumothorax are uncommon findings. Sometimes airspace consolidation or hemorrhage may also develop. The most common findings include bilateral perihilar peribronchial thickening and interstitial infiltrates which, particularly in children, due to their small-caliber airways, can result in areas of atelectasis or air trapping. It is especially associated with patients living in close community settings. Mycoplasma pneumoniae ( mycoplasma pneumonia) is the causative organism in up to 20 of CAP and is often seen in paediatric populations and young adults 3. Radiographic features Plain radiograph / CT Atypical pneumonia makes up a significant proportion of community-acquired pneumonia (CAP). human papillomavirus (HPV): HPV pneumonia.Epstein-Barr virus (EBV): EBV pneumonia.varicella-zoster virus (VZV) (β herpesvirinae): varicella pneumonia.cytomegalovirus (α herpesvirinae): cytomegalovirus pneumonia.herpes simplex virus type 1 (HSV1) pneumonia.Middle East respiratory syndrome coronavirus (MERS-CoV) infection.coronaviridae - human coronaviruses (hCoV).enterovirus: enterovirus respiratory tract infection.echovirus: echovirus respiratory tract infection.coxsackievirus: coxsackievirus respiratory tract infection.mumps: respiratory tract infection from mumps.measles: respiratory tract infection from measles.They can be caused by any of a large number of viral agents, including but not limited to: RNA viruses Viral respiratory tract infection is a broad term given to pulmonary infection caused by viruses. ![]()
