case_images: An imaging study with a plain radiograph of the cervical spine showed a large area of prevertebral soft tissue swelling from C1 to C5 and focal calcifications anterior to the C1 (Fig. 1).
case_images: Sagittal T2 weighted MR image shows the high signal retropharyngeal effusion with acute inferior margin extending from the skull base to the inferior border of C5 (white arrow).

case_images: A sagittal T2 weighted MR image showed a high signal retropharyngeal effusion with acute inferior margin extending from the skull base to the inferior border of C5 (Fig. 2).
case_images: Bone sagittal view of contrast-enhanced computed tomography shows retropharyngeal fluid collection and three calcific deposits anterior to the C1-C2 level (white arrow).

case_images: A cervical CT was performed with contrast medium and the bone sagittal view revealed retropharyngeal fluid collection and three calcific deposits anterior to the C1-C2 level (Fig. 3).
case_images: Nasopharyngolaryngoscopy shows posterior pharyngeal wall swelling overlying arytenoids (white arrow).

case_images: Because of dysphagia and odynophagia complaints, we consulted the otolaryngologist and he performed a flexible nasopharyngolaryngoscopy which showed posterior pharyngeal wall swelling in the arytenoid (Fig. 4).
case_images: Follow up lateral view of the cervical plain radiograph showed much improved prevertebral swelling.

case_images: During two months of follow-up visits, the symptoms were resolved without any significant sequelae, and the follow-up radiograph showed that the preverteral swelling was much improved (Fig. 5).
