A case of Primary Retroperitoneal Teratoma, Including the Upper Pole of the Left Kidney / 대한비뇨기과학회지

ABSTRACT

A case of retroperitoneal teratoma in a 37-year old woman is presented. For approximately 20 years, she suffered from a slowly growing palpable mass and discomfort and pain in the LUQ. Upper GI series revealed compression and displacement of the greater curvature of the body of the stomach, and the outline of a large LUQ. mass overlapping the left kidney. IVP demonstrated compression of the left renal pelvis and calyceal system by this large mass, and considerable amorphous calcification in the upper pole of the mass. Pre-operatively, the mass was suspected to be a dermoidcyst or teratoma or pancreatic pseudocyst. At the operation, it proved to be a large retroperitoneal tumor mass of infant-head size, and it extended to the pancrestic hilum, including the upper pole of the left kidney, with adhesion to the left mesocolon. This huge tumor mass and involved left kidney were widely removed.
