Pulmonary capillary hemangiomatosis is a rare cause of pulmonary hypertension characterized by extensive proliferation of pulmonary capillaries within alveolar septae. Clinical presentation is nonspecific and includes dyspnea, cough, chest pain, and fatigue. Radiology shows diffuse centrilobular ground-glass opacities. Pulmonary capillary hemangiomatosis is clinically and radiographically indistinguishable from peripheral venoocclusive disease, making microscopic diagnosis essential. Histologically, pulmonary capillary hemangiomatosis shows an abnormal proliferation of small, thin-walled capillaries that expand the alveolar septae. The endothelial cells that comprise these lesions are cytologically bland and show no mitotic activity. Pulmonary capillary hemangiomatosis is important to recognize because prostacyclin therapy, a mainstay in the treatment of pulmonary hypertension, has been reported to cause sudden respiratory distress and death in these patients. Prognosis of this disease remains poor, and the only definitive treatment is lung transplantation.

“…It was once believed to be caused by aspiration of purulent discharge in the paranasal sinuses. However, altered immune status is now considered to lead to both paranasal sinusitis and infectious bronchiolitis [43] . Chest radiograph shows reticulonodular opacities with lower lung field predominance ( Figure 9).…”

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.
