While plain X-rays showed scalloping of the C5 vertebral body, magnetic resonance imaging (MRI) demonstrated a large lobulated retropharyngeal mass (7.5 cm craniocaudal x 4.8 cm transverse 4.8 cm x 3.1 cm AP) compressing the upper airway (i.e., oropharynx and hypopharynx) [Figures 1 and 2].
Contrast magnetic resonance imaging scan of cervical spine: a large mass arising in the retropharyngeal space with bright signal intensity.

The lesion was hypointense on T1- and hyperintense on T2-weighted images [Figures 3 and 4].

The lesion was hypointense on T1- and hyperintense on T2-weighted images [Figures 3 and 4].
Intraoperative examination: intraoperative examination shows a large bulging plurilobulated mass with central location and remarkable reduction of the oropharyngeal space with the showing gray-white firm appearance.

Utilizing a routine right-sided Smith-Robinson approach, the C2 to C5 lesion was routinely excised [Figures 5 and 6].
Intraoperative examination: complete surgical excision of mass before wound closure with drain in situ.

Histopathology slide: the tumor shows plexiform multinodular appearance with bland spindle cells.

Histologically, the tumor showed nodular plexiform fragments, bland spindle cells with nuclear palisading and verocay bodies, and all diagnostic for a benign plexiform schwannoma [Figures 7 and 8].
Histopathology slide: characteristic nuclear palisading verocay bodies are seen.
