With ultrasound of the neck a non-specific hypoechoic mass could be correlated (Fig. 1).
Contrast-enhanced MRI of the head and neck showed the full extent of nasopharyngeal RMS. Left: coronar view, T1-weighted. Right: axial view, T2-weighted. The arrows point to the tumor.

A contrast-enhanced MRI of the head and neck was performed and revealed a 6.1 cm x 3.1 cm x 7.0 cm well-circumscribed, homogeneous, contrast-enhanced tumor extending from the left-sided skull base to supraglottic structures (Fig. 2).
Contrast-enhanced CT angiography showed lateralization of the carotid artery and indentation of the internal jugular vein but ruled out infiltrative tumor growth and bone erosion. Left: coronar view. Right: axial view. The arrows point to the tumor.

Additionally, a contrast-enhanced CT angiography showed the lateralization of the carotid artery and indentation of the internal jugular vein but ruled out infiltrative tumor growth and bone erosion (Fig. 3).
