title: [Pulmonary lymphomatoid granulomatosis radiologically mimicking interstitial pneumonia].
abstract: We report a rare case of pulmonary lymphomatoid granulomatosis radiologically mimicking interstitial pneumonia. A 57-year-old man was admitted to our hospital because of chest bilateral reticular shadow with sustained cough and breathlessness for 10 years. Chest CT scans showed multiple ground-glass opacities, traction bronchiectasis and cystic change in both lungs, in addition to hilar and mediastinal lymphadenopathy. A histopathologically diagnosis of pulmonary lymphomatoid granulomatosis (angiocentric immunoproliferative lesion, grade 1) was made by thoracoscopic lung biopsy. In this case, serological and immunohistochemical analyses did not show Epstein-Barr virus infection. No clinical or radiological deterioration has been observed thereafter despite no medication.
