[Inflammatory pseudotumor of the lung]

An inflammatory pseudotumour of the lung was occasionally observed at radiology and is reported. Such lesions account for 1% of all lung tumours and are frequently asymptomatic; the findings on physical and laboratory examinations are usually nonspecific. Radiographic findings and invasive diagnostic procedures--including bronchoscopy and transthoracic fine needle biopsy--may be not sufficient for histological diagnosis. Surgery is then important for both diagnostic and therapeutic reasons; the treatment of choice is complete but non extensive excision. Radiotherapy should be considered in patients who had incomplete surgical resection or postoperative recurrences and in patients non resectable due to associated medical conditions.
