Abstract
Carotid body paraganglioma is commonly asymptomatic, slow‐growing, and nonfunctioning. With its relative contraindication to biopsy due to its high vascularity in nature, imaging characteristics are the key to help making the diagnosis. Treatment modalities, ranging from an observation to definitive treatment with surgery, should be selected on an individual basis.
Highlights
Flow‐void sign with salt‐and‐pepper appearance was noted
MR angiography demonstrated a tumor splaying at the carotid bifurcation (Figure 1D)
Flow‐void sign is a feature of the hypervascularity of the lesion, which results in multiple signal drop (“pepper”) areas interspersed with hyperintense (“salt”) foci.[1]
Summary
A 53‐year‐old woman presented with a painless pulsatile left neck mass. MRI study revealed a 2.7 × 3.1 × 3.9 cm well‐ circumscribed hypervascular mass at left carotid bifurcation.
