Case Series of Head and Neck Paragangliomas: Radiological Diagnosis and Clinical Characteristics

Paragangliomas are neuroendocrine tumors arising from extra-adrenal paraganglionic tissue with characteristic anatomic distribution in the head and neck. These include carotid body paragangliomas, tympanic paragangliomas, jugular/jugulotympanic paragangliomas and vagal paragangliomas. This case series compiles radiological features, clinical presentation and treatment strategies from documented imaging and clinical sources. Emphasis is placed on imaging modalities and their diagnostic value in treatment planning and tumor characterization. This summary integrates evidence and case illustrations to emphasize the importance of early recognition and the role of multimodal radiologic assessment.
