Post-styloid parapharyngeal neurogenic tumors: imaging-based prediction of nerve origin and clinical outcomes — a single-center retrospective case series
To evaluate the precision of imaging-derived nerve-of-origin predictions utilizing vessel displacement patterns, in relation to intraoperative validation.
Approach:
Key Findings:
Fifteen individuals (average age 44.5 years; 67% male) were recognized.
A non-tender cervical mass was the most prevalent presenting symptom (53%).
Imaging indicated a vagal source in 11 tumors and a sympathetic chain source in 4 tumors.
Imaging accurately predicted the nerve of origin in 8 out of 9 patients (88.9%) who underwent surgical intervention, with one misidentified as vagal but confirmed as sympathetic intraoperatively.
Postoperative complications included vocal fold paralysis and Horner's syndrome in one patient each.
Interpretation:
Regular cross-sectional imaging of vessel displacement patterns could assist in the preoperative evaluation of nerve origin for post-styloid PPS neurogenic tumors.
Limitations:
The study is based on a small sample size from a single institution, and further multicenter investigations with larger cohorts are required to validate these findings.
Conclusion:
Imaging-derived predictions of nerve origin may assist in surgical planning and risk assessment for patients with post-styloid PPS tumors.
