CT Right Sided Anterior Mediastinal Teratoma
47-year-old female presents with an abnormal CXR
CT scan in the coronal projection shows a 6.3X 5.9 x 6.8cms mass in the anterior mediastinum that shows central fatty elements, surrounded by intermediate density of homogeneous soft tissue elements and a prominent calcification with a shape reminiscent of a tooth, and a more heterogeneous infero-lateral rim of soft tissue density with punctate calcifications.. These findings are consistent with a teratoma
