Summary
Vagal paragangliomas are rare tumors. This case highlights a non-functioning vagal paraganglioma in the lower neck, emphasizing the need for surgical awareness beyond typical locations.
Area of Science:
- Neuro-oncology
- Surgical Pathology
Background:
- Paragangliomas are rare, typically benign tumors originating from neural crest tissue.
- Vagal paragangliomas constitute a small subset (3%) of head and neck paragangliomas, usually found in the upper vagus nerve.
Purpose of the Study:
- To report a rare case of a non-functioning vagal paraganglioma in the infra-hyoid carotid sheath.
- To increase awareness among head and neck surgeons regarding unusual locations of vagal paragangliomas.
Main Methods:
- Diagnostic imaging including ultrasonography, computed tomography, and magnetic resonance imaging were utilized.
- Surgical resection of the tumor along with the affected vagus nerve segment was performed.
Main Results:
- Imaging findings were suggestive of paraganglioma.
- The tumor was intimately associated with the vagus nerve, necessitating en bloc resection.
Conclusions:
- Vagal paragangliomas can present in the lower neck, deviating from the common rostral location.
- Surgeons managing head and neck masses should consider paraganglioma in the differential diagnosis, even in atypical anatomical sites.

01:18Cranial Part of Parasympathetic Division
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
