Abstract Objective: To summarize the CT features of pulmonary hamartoma without typical calcified, in order to improve the clinical diagnostic accuracy. Methods: Retrospective analysis with 11 cases of pulmonary hamartoma confirmed by pathologically from June 2008 to October 2013. Ten patients underwent dynamic contrast-enhanced CT scans, 1 patient underwent ordinary routine CT scan. Results: A total of 11 cases of which 7 cases occurred in right lung, 3 cases in left lung, 1 case in the trachea. the tumor size range from 0.7 cm × 0.7 cm to 3 cm × 2.5 cm, with an average diameter of 1.8 cm. Fat density could be detected in 3 cases, 6 cases showed the soft tissue density. Calcification density couldn’t be measured in all lesions. Six cases of nodules showed the lobulation sign, but all of the tumors showed no spiculation sign and no pleural indentation sign and no vascular convergence sign. After dynamic enhancement, 9 cases enhanced CT values were less than 20 HU, 1 case enhanced CT values between (30～40) HU. Conclusion: The pulmonary hamartoma without typical calcified shows the benign tumor characteristics. The lobulation sign is relatively common, so it is easily be misdiagnosed as lung cancer, in thin slice CT scan, the small fat particles can make a definite diagnosis.
