Özet

Paragangliomas are extremely rare chromaffin cell tumors arising from neural crest cells. Extra-adrenal paragangliomas originate from paravertebral and para-aortic paragangliomas distributed from the skull base to the pelvic floor. Here, we report a 57-year-old woman who presented with abdominal pain. Computed tomography revealed a solid mass at the renal hilum. The extent of disease was evaluated with 2-[18F]-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET). Increased uptake of 18F-FDG was observed in the mass. The patient underwent diagnostic laparotomy, but the tumor was unresectable due to its close relationship with vascular structures. Pathologic examination confirmed that the tumor was a benign paraganglioma. To our knowledge, this location is extremely rare, and there are limited data reporting the value of PET scanning in the diagnosis of paragangliomas.
