The value of conventional radiography and computed tomography (CT) in diagnosis of pulmonary hamartoma.
No radiologic features are pathognomonic for hamartoma of the lung. Punctate or popcorn calcification, umbilication sign and CT density measurements should be helpful but are not diagnostic. Evidence of fat may suggest pulmonary hamartoma and CT density measurements may be helpful to detect this. A low CT number, however, may be the result of either the partial volume averaging or the presence of fat in the tumour. The definite diagnosis can be made only by histological examination after thoracotomy or transthoracic puncture.
