Abstract
- Paraganglioma, a pheochromocytoma arising in extra-adrenal tissue, is less common and more difficult to characterize radiologically. This disease has higher incidence of nonfunctioning and malignancy than adrenal pheochromocytoma, and occurs multiple. mostly around renal hilum. A 35-year-old female was transferred to our hospital complaining of palpable mass on the LUQ for 3 years. On admission, child head-sized fixed hard mass was palpated on LUQ. Urinary VMA, serum catecholamine and other tumor markers were within normal limit. Ultrasonogram and abdominal CT demonstrated inhomogeneous enhanced tumor mass located anteriorly to left kidney. En bloc removal of the mass with ipsilateral kidney and regional lymphadenectomy were done. We confirmed postoperatively the benign nonfunctioning retroperitoneal paraganglioma by histopathological studies.
