case_images: No enlarged cervical lymph node was seen (Figure 1).
case_images: (a, b) An MRI image of the same mass. (c) MRI angiography demonstrates a highly vascular mass splaying the internal and external carotid arteries.

case_images: MRI angiography also revealed splaying of the carotid vessels at the carotid bifurcation with multiple feeders (Figures 2(a)-2(c)).

case_images: A hemorrhagic mass, firm in consistency with significant bleeding on contact due to multiple varicose vessels, was seen all over it (Figure 3).

case_images: He is alive with a healed scar along the line of the skin incision (Figure 5).
case_images: Histological section showing nested packets of mild to moderately pleomorphic tumor cells (arrows) having hyperchromatic central nuclei and moderate eosinophilic, faintly granular cytoplasm consistent with the features of paraganglioma (H&E x40).

case_images: Also seen were areas of stromal hyalinization, focal necrosis, and hemorrhage (Figure 6).
case_images: (a) Chromogranin, (x40) immunohistochemical stain (3+) in about 80% of the tumor cells in keeping with a diagnosis of paraganglioma. (b) Synaptophysin, (x40) immunohistochemical stain showing positive diffuse cytoplasmic staining (3+) in about 95% of the tumor cells in keeping with a diagnosis of paraganglioma.

case_images: The immunohistochemisty result revealed reactivity of tumor cells to chromogranin, neuron-specific enolase, and synaptophysin stains (Figure 7).
