Carotid Body Glomus Tumor (Glomus Caroticum; Carotid Body Paraganglioma)

Figure 1: The low signal intensity mass splaying the right internal and external carotid artery on T1WI (top row left) is in a typical location for carotid body paraganglioma. This lesion tends to be hyperintense on T2WI (top row right) containing low-signal intensity flow voids due to its high vascularity. The lesion enhances avidly on postcontrast imaging (bottom) due to this feature of hypervascularity as well.   Figure 2: T1FS Post-Contrast (top row left) and T2FS (top row right) images demonstrate an avidly enhancing mass with associated internal flow voids splaying the left internal and external carotid arteries in a patient with multiple paragangliomas. Digital subtraction angiography (bottom row left) performed prior to embolization demonstrates a hypervascular mass splaying the left internal and external carotid arteries. Following embolization a whole body 68Ga-DOTANOC PET/CT (bottom row right) was performed to assess for additional sites of disease. 68Ga-DOTANOC locali...
