Paragangliomas, also known as glomus tumours, are rare tumours that arise from paraganglionic tissue. They most commonly occur in the middle ear, jugular foramen, and along the vagus nerve. Surgical resection is the primary treatment, but pre-operative embolization and radiotherapy can help reduce tumour size and vascularity. Complete surgical removal is difficult due to the complex anatomy of the skull base and risk of damaging nearby cranial nerves. Adjuvant radiotherapy is often used post-operatively to prevent tumour regrowth. Functionally active tumours can cause issues with blood pressure control and circulatory collapse during and after surgery.
