Case Report: The patient is a 60-year-old male with a history of dyspnea and surgical removal of kidney stonein 1 year ago. Results: In chest-X-ray prior to the surgery an olive-shaped homogenous density, with a size of 30 mm × 20 mm in the right lung have been detected. Computed tomography (CT) scan has been performed, and a homogenous mass with a well-delineated border in major fissure of the right lung and mediastinal lymphadenopathy had been detected. Serial CT scans revealed mass enlargement. In Ct guided, Transthoracic biopsy fluid collection along the major fissure of the right lung had been detected. Biopsy of mediastinal lymph node silicoanthracotic changes with focal hyaline fibrosis had been shown. Conclusions: The diagnosis of the phantom tumor must be considered in any patient with congestive heart failure and lung mass. In this patient, there was no history of congestive heart failure which shows that phantom tumor could happen in non-chronic heart failure patients. Although the accurate diagnosis of the phantom tumor with imaging modalities in patients without congestive heart failure is very difficult but at least this diagnosis must be considered in a patient with a lung mass in the major fissure of the lungs. https://ajs.tums.ac.ir/index.php/ajs/article/view/41 https://ajs.tums.ac.ir/index.php/ajs/article/download/41/31
