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).
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).

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).
Nasopharyngolaryngoscopy shows posterior pharyngeal wall swelling overlying arytenoids (white arrow).

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).
Follow up lateral view of the cervical plain radiograph showed much improved prevertebral swelling.

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).
