Fig. 1.
A. Horizontal sections: A hypoechoic well-delineated borders nodule of compound structure at the peripheral section of the common carotid artery. B. Vertical sections: A distinct lesion measuring 28 × 24 mm, causing dilatation of the internal and external carotid arteries in their course. Increased vascularity with the use of color Doppler from external carotid branches in their course
Fig. 2.
A. CT axial sections after iv enhancement: Nodule with clear distinct borders and homogeneous intake of contrast media in the arterial phase. B. Postoperative image with the lack of residual tissue as well as the lack of pathological enhancement in the area
Fig. 3.
MRI axial, coronal and MRA images: High signal tumor with characteristic salt and pepper image from the dilatation of intermediate signal vessels in the lesion content
Fig. 4.
Frontal sections: Compound 38 × 26 mm tumor in the submandibular area with low echogenicity, homogeneous texture and high vascularity in Power Doppler
Fig. 5.
A. Angulated sections: At the level of the submandibular gland the lesion causes shift of the carotid space vessels towards the inner structures. B. Frontal sections: The GT of the vagus nerve causes alterations in the course of the internal and external carotid artery decreasing their in between distance
Fig. 6.
Coronal MRI T1-W sections demonstrated glomus tumor at the level of vagal nerve with high signal of the lesion with clear borders and no adjacent tissue involvement
