Spontaneous obliteration of right ventricular pseudoaneurysm after blunt chest trauma: diagnosis and follow-up with multidetector CT.
Right ventricular (RV) pseudoaneurysm caused by trauma is very rare. We report a case of RV pseudoaneurysm which resolved without surgical treatment in a patient who survived a falling accident. Echocardiography failed to identify the pseudoaneurysm. Electrocardiography-gated CT showed a 17-mm-sized saccular pseudoaneurysm arising from the RV outflow tract with a narrow neck. Follow-up CT after two months showed spontaneous obliteration of the lesion.
