“…Random nodules are probably produced by hematogenous spread of the disease [1] or granulomatous infection. Some viral pneumonia epitomized by varicella-zoster pneumonia can assume this pattern ( Figure 15) [11] . Hematogenous dissemination of pathogens such as military tuberculosis (Figure16) [12] or septic emboli ( Figure 17) [13] also falls in this category.…”

“…Among them, bronchopneumonia and GGO predominance are the most common presentations of viral pneumonia ( Figure 13) [4] . Random nodule pattern is characteristic of varicella-zoster (VZ) pneumonia ( Figure 15) [11] although military tuberculosis or mycosis, or bacterial emboli shares this finding. It is conceivable that random nodules seen in VZ pneumonia are due to the fact that VZ hematogenously infects the lung [26] .…”

“…It is conceivable that random nodules seen in VZ pneumonia are due to the fact that VZ hematogenously infects the lung [26] . Scattered small nodules with calcification are also sometimes seen in patients with a past history of VZ pneumonia [11,26] . Mixed infection, namely accompanying bacterial pneumonia, is also common in viral pneumonia.…”

This article reviews roles of imaging examinations in the management of community-acquired pneumonia (CAP), imaging diagnosis of specific CAP and discrimination between CAP and noninfectious diseases. Chest radiography is usually enough to confirm the diagnosis of CAP, whereas computed tomography is required to suggest specific pathogens and to discriminate from noninfectious diseases. Mycoplasma pneumoniae pneumonia, tuberculosis, Pneumocystis jirovecii pneumonia and some cases of viral pneumonia sometimes show specific imaging findings. Peribronchial nodules, especially tree-in-bud appearance, are fairly specific for infection. Evidences of organization, such as concavity of the opacities, traction bronchiectasis, visualization of air bronchograms over the entire length of the bronchi, or mild parenchymal distortion are suggestive of organizing pneumonia. We will introduce tips to effectively make use of imaging examinations in the management of CAP. Key words: Community-acquired pneumonia; Computed tomography; Infection; Pneumonia; Lung disease Core tip: This review article discusses imaging diagnosis of community-acquired pneumonia (CAP). As imaging findings of CAP are considered nonspecific, this topic is rarely focused on in radiology journals. However, we believe that imaging examinations contribute much more than generally considered if detailed evaluation of the imaging findings is made. In this article, we will introduce tips to effectively make use of imaging examinations in the management of CAP. Nambu A, Ozawa K, Kobayashi N, Tago M.

“…El adenovirus también produce nodulillos centrilobulillares, pero tiene un mayor compromiso parenquimatoso con atelectasias y bronquiolitis, caracterizándose por áreas de retención de aire y defectos de perfusión. Muchas veces hay bronquiectasias asociadas que pueden quedar como secuelas; es frecuente la efusión pleural (63%) 58,59 . Citomegalovirus es frecuente en pacientes inmunocomprometidos que han sido sometidos a trasplantes y en SIDA, habiéndose invocado mecanismos patogénicos diferentes en estos dos grupos.…”
