OR
There are no CT scan findings associated with [disease name]. However, a CT scan may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].
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 homogeneous and intense enhancement after intravenous administration of contrast dye.
- large tumors tend to appear in-homogeneous 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.
CT angiography
Findings diagnostic of carotid body tumor include:[2]
- A hypervascular mass with enlarged feeding arteries
- Intense tumor blush due to high vascular content
- Early venous drainage
