Dynamic CT features of mediastinal hemangioma: more information for evaluation

Dynamic enhancing feature in mediastinal hemangioma was rarely reported. Slow, gradually increasing and prolonged contrast stains are the diagnostic hints in our case that avoid the hemorrhagic catastrophe from transthoracic core needle biopsy. A rare finding of an aberrant vessel entering into the tumor was valuable for operative planning. Dynamic computed tomography (CT) can provide more information for evaluation in such cases.
