Constrictive pericarditis from an embolized hypodermic needle: radiographic, CT and MR imaging findings.
We present the radiographic, computed tomographic (CT), and magnetic resonance (MR) findings in a woman with constrictive pericarditis due to an embolized hypodermic needle. The chest films revealed pleural effusions but no foreign body. The CT showed pericardial thickening and a linear foreign body of metallic attenuation in the right ventricular apex, and MR imaging revealed a signal void with magnetic susceptibility artifact. This case illustrates the capabilities and limitations of CT and MR imaging in hypodermic needle-induced constrictive pericarditis.
