Summary
Rare vagal paragangliomas present diagnostic challenges in the head and neck. This report details two cases, highlighting diagnostic approaches and surgical findings for these unusual tumors.
Area of Science:
- Neurosurgery
- Oncology
- Head and Neck Surgery
Background:
- Paragangliomas are rare neuroendocrine tumors originating from neural crest cells.
- Head and neck paragangliomas, particularly those arising from the vagus nerve, are exceptionally uncommon and pose diagnostic difficulties.
Observation:
- The first case involved an intravagal tumor suspected via angiography, confirmed by biopsy after surgical exploration.
- The second case presented as a diagnostic surprise, initially suspected as parotid swelling, but intraoperatively found to originate from the vagus nerve.
Findings:
- Both cases confirm the existence and surgical management of paragangliomas originating within the vagus nerve.
- Diagnostic imaging and intraoperative findings were crucial in identifying the tumor's origin and extent.
Implications:
- These cases underscore the importance of considering rare differentials like vagal paragangliomas in head and neck swellings.
- Enhanced awareness and diagnostic vigilance are necessary for timely and accurate diagnosis of these challenging tumors.
