Mediastinal hemangioma: radiographic and CT features in 14 patients.

Journal Article (Journal Article)

PURPOSE: To characterize the imaging features of mediastinal hemangioma. MATERIALS AND METHODS: The authors retrospectively reviewed chest radiographs and computed tomographic (CT) scans from 14 patients with mediastinal hemangioma. RESULTS: Most mediastinal hemangiomas manifested as well-marginated masses at CT. Three masses had punctate calcifications, and one had phleboliths. Five masses were of heterogeneous attenuation at unenhanced CT. Ten of 11 (91%) hemangiomas were of heterogeneous attenuation at contrast material-enhanced CT, and the following four patterns were observed: central (n = 6, 60%), mixed central and peripheral (n = 2, 20%), peripheral (n = 1, 10%), and nonspecific (n = 1, 10%) increased attenuation. Central increased attenuation was observed more frequently after administration of a bolus of contrast material than after slow infusion. CONCLUSION: Hemangiomas should be considered in the differential diagnosis of well-marginated mediastinal masses that have heterogeneous attenuation on CT scans, show central enhancement after administration of contrast material or contain punctate calcification.
