Intrarenal Teratoma

Abstract

Editor's Note.-Everyone who has taken the course in radiologic pathology at the Armed Forces Institute of Pathology (AFIP) remembers bringing beautifully illustrated cases for accession to the Institute. In recent years, the staff of the Department of Radiologic Pathology has judged the ''best cases'' by organ system, and recognition is given to the winners on the last day of the class. With each issue of RadioGraphics, one or more of these cases are published, written by the winning resident. Radiologicpathologic correlation is emphasized, and the causes of the imaging signs of various diseases are illustrated.

Mature Cystic Renal Teratoma

“…The preoperative differential diagnosis of children with an intrarenal teratoma includes Wilms’ tumor, neuroblastoma, hydronephrosis, retroperitoneal teratoma, unspecified tumor, and infected renal cysts. For adults, the list includes unspecified tumors and renal cell carcinoma (4). Teratomas are usually benign.…”

Renal teratoma with duplication of cecum and appendix

“…In one review, only 12 such tumors have been reported in children [2]. In the same review article, the authors mentioned 8 cases of intrarenal teratomas in adults [2]. Ledo et al [4] reported renal teratoma in an infant.…”

“…We could not find a similar association previously reported in the English literature. Various congenital anomalies have been reported with renal teratoma [2,6]. Developmental anomalies increase the risk of teratoma [2].…”

“…Various congenital anomalies have been reported with renal teratoma [2,6]. Developmental anomalies increase the risk of teratoma [2]. In another review, 10 cases of teratoma were found in rare sites [7].…”

“…Renal teratoma is an exceedingly rare condition [2]. Teratomas commonly arise in the gonads, sacrococcygeal region, brain, and retroperitoneum.…”
