We present the dynamic contrast-enhanced computed tomography (CT) findings of atypical pulmonary hamartoma with a rare histologic pattern in a 20-year-old male. CT showed a 3.4 cm lobulated mass with a 'tip of the iceberg' appearance in the medium bronchus of the right lower lobe. Dynamic contrast-enhanced CT demonstrated a heterogeneously and persistently enhancing mass. The CT Hounsfield unit (HU) measurements were: 17 HU pre-contrast, 32 HU at 1 minute, 44 HU at 2 minutes, 51 HU at 4 minutes, and 64 HU at 15 minutes. Pathologic examination after video-assisted thoracoscopic surgery disclosed a pulmonary hamartoma with a predominant fibroblastic component.
