RESUMEN
Objective To investigate the imaging features of acute interstitial pneumonia and to provide the reference for early diagnosis and treatment.Methods The imaging and clinical data of 50 patients with clinically diagnosed acute interstitial pneumonia in our hospital were analyzed retrospectively.Results X-ray film showed the fan-shaped and lightly patchy shadows around the lung hilum distributing along the lung markings in multiple lung fields,accompanied by thickening of interlobular septa with varying degrees and thickened bronchial vascular shadows running through the above-mentioned light patchy shadows.CT revealed the fan-shaped ground glass opacity in the pulmonary area with rich blood supply,interspersed with thickened clustered pulmonary arteries and veins.Conclusion The imaging features of acute interstitial pneumonia have certain characteristics.The suggestive diagnosis based on imaging plays an important guiding role in early clinical diagnosis and treatment.
