Para-aortic paraganglioma: Preoperative embolization and surgical resection.

Retroperitoneal paragangliomas are neuroendocrine tumors originating from chromaffin cells in the sympathetic nerves. These tumors are commonly located around the abdominal aorta and inferior vena cava and can cause significant bleeding during surgery due to their hypervascular nature. In such cases, preoperative selective embolization can facilitate tumor resection and reduce both morbidity and mortality. This case report presented a 38-year-old male patient with a retroperitoneal paraganglioma who underwent surgery following preoperative embolization due to tumor hypervascularity.
