Surg Neurol Int. 2020 Jul 11:11:182. doi: 10.25259/SNI_317_2020. eCollection 2020.

Abstract

Background: Approximately 25-45% of schwannomas are typically slow-growing, encapsulated, and noninvasive tumors that occur in the head-and-neck region where they rarely involve the retropharyngeal space. Here, we report deep-seated benign plexiform schwannoma located in the retropharyngeal C2-C5 region excised utilizing the Smith-Robinson approach.

Case description: A 30-year-old male presented with dysphagia and impaired phonation attributed to an MR documented C2-C5 retropharyngeal schwannomas. On examination, the lesion was soft, deep seated, and extended more toward the right side of the neck. Utilizing a right-sided Smith-Robinson's approach, it was successfully removed. The histopathology confirmed the diagnosis of a plexiform schwannoma.

Conclusion: Retropharyngeal benign plexiform schwannomas are rare causes of dysphagia/impaired phonation in the cervical spine. MR studies best document the size and extent of these tumors which may be readily resected utilizing a Smith-Robinson approach.
