Abstract Objective: To investigate and discuss the imaging features of cavernous hemangiomas of mediastium(CHM). Methods: The CHM images of four patients who underwent force CT enhanced scan were retrospectively analyzed, and then showed the direct signs of the disease through various CT post-processing reconstruction techniques. One of them underwent magnetic resonance imaging. Results: The mass was located in the anterior, middle, posterior mediastinum and mediastinal multiregion, each containing one case. Three lesions were unevenly distributed, and calcification or vein stone was found by CT scanning. One was homogeneous, and flow void of the vessels was identified by MRI examination. The boundary is clear in three cases, and the boundary of one case is unclear. In four cases of CT enhanced scan, mild inhomogeneity was enhanced and delayed scan was further enhanced, of which two cases were enhanced by vascular lake like, and abnormal drainage veins were found in four cases. Conclusion: The CT enhancement scan is of great value and the post-processing technique can show more details for CHM lesions. CHM image characteristics can be summarize as delayed enhancement, with calcification or vein stone, abnormal drainage vein, and vascular lake enhancement. T2WI fat suppression image is characterized by high signal.
