Overview

Cervical CT scan may be helpful in the diagnosis of the carotid body tumor. Findings on CT scan suggestive of/diagnostic of carotid body tumor include a well-defined, hypervascular mass which will show homogeneous and intense enhancement after intravenous administration of contrast dye.

CT scan

• The carotid body tumor has the following characteristic feature on the CT scan:
  • 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:

• A hypervascular mass with enlarged feeding arteries
• Intense tumor blush due to high vascular content
• Early venous drainage
• Splaying of the carotid vessels
