Abstract
|
|
|
Paraganglioma, a pheochromocytoma arising in extra-adrenal tissue, is less common an dmore 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 inhomogenous 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.
