Many pathogens can infect the lungs and cause pneumonia in immunocompetent patients. These agents include bacteria, but also viruses, fungi and parasites. Recognising the radiological patterns on chest X-rays and CT scans is crucial to identifying the causative pathogens and possible
complications, and thus improving the clinical management strategy. An accurate approach facilitates the administration of effective therapies, which can significantly improve the patient’s prognosis.
