CT scan
- The carotid body tumor has the following characteristic feature on the CT scan:[1]
- A well-defined, soft tissue mass within the carotid space
- The mass splays the internal and external carotid arteries (Lyre sign)
- Since the tumor is highly vascular, It will show homogenous and intense enhancement after intravenous administration of contrast dye.
- large tumors tend to appear inhomogeneous with some areas of hemorrhage as well as necrosis.
- The tumor usually is in the infrahyoid space, however, it may enlarge to an extent that be present in the suprahyoid space in 8% of the cases as well.
