The authors present the imaging findings in a 44-year-old woman with a rare intercostal hemangioma that originated from the connective tissue between the intercostal muscle and parietal pleura and protruded into the thoracic cavity. The contrast-enhanced computed tomography (CT) showed a markedly enhancing mass, whereas dynamic magnetic resonance (MR) images showed heterogeneous and strong enhancement with incomplete early eccentric enhancement peripherally followed by complete filling-in on delayed scans. The imaging features of CT and MR imaging of a hemangioma may be useful for proper preoperative diagnosis.
