CT scan

• Enhanced CT is the imaging modality of choice for carotid body tumor.
• On CT scan, carotid body tumor is characterized by the following findings:

• Soft tissue density on non-contrast CT (similar to muscle)
• Bright and rapid (faster than schwannoma) enhancement
• Splaying of the internal carotid artery and external carotid artery.

• Radiological signs for carotid body tumor, include:

• Lyre sign : defined as the splaying of the internal and external carotid by a carotid body tumour (visible on CT angiography)
