"In macroscopic emboli, both bland and tumour emboli can appear as focal hypo-attenuating pulmonary arterial filling defects on CT pulmonary angiography. Further differentiation can often be difficult unless a specific substance such as fat or calcific content is seen in the appropriate clinical context (e.g. angiomyolipoma and osteosarcoma)."
