A 79-year-old woman with a history of temporal arteritis and hypothyroidism underwent contrast-enhanced chest CT for evaluation of mediastinal mass incidentally noted on neck CT performed for pulsatile neck mass (which turned out to be a tortuous carotid artery). Axial CT image demonstrated a low-density anterior mediastinal mass (12 HU) abutting the pulmonary arterial trunk with partially calcified wall (arrow). Adjacent thymic tissue was visible on CT (arrowhead).
