Summary
Imaging features of head and neck paragangliomas are reviewed. Pre-operative embolization significantly reduces surgical complications, aiding in diagnosis and management.
Area of Science:
- Radiology
- Oncology
- Head and Neck Surgery
Context:
- Paragangliomas are rare neuroendocrine tumors.
- Head and neck paragangliomas present diagnostic challenges.
- Multimodality imaging is crucial for characterization.
Purpose:
- To review imaging findings of head and neck paragangliomas.
- To assess the efficacy of pre-operative embolization in managing these tumors.
Summary:
- Thirty-three paragangliomas in 30 patients were evaluated using ultrasound, CT, MRI, and angiography.
- Common locations included the carotid body (16), temporal bone (14), and vagus nerve (3).
- Pre-operative embolization was performed in 22 cases, primarily as an adjunct to surgery, reducing complications.
Impact:
- Imaging is vital for diagnosing head and neck masses.
- Pre-operative embolization improves surgical outcomes by minimizing intra-operative bleeding.
- This approach enhances the management of paragangliomas.
