These tumors most commonly seen at the gonadal and sacrococcygeal regions. Herein we describe a case of an 18-year-old female who had a benign cystic teratoma at the retroperitoneum.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>PRESENTATION OF CASE:<\/jats:title>\n                    <jats:p>\n                      The patient underwent an operation at another hospital following a misdiagnosis of hydatid cyst. The patient was referred to our hospital because of the detection of an unresectable tumor during her operation. A computerized tomography (CT)\u2013angiography revealed a cystic mass, with a diameter of 14 cm which was invaded into the retrohepatic suprarenal inferior vena cava and also extended to the posterior aspect of the liver. Additionally the mass invaded the posterior wall of the inferior vena cava and the right renal vein. The tumor was completely resected with a vascular resection. The inferior vena cava was reconstructed with a 12 cm Dacron\n                      <jats:sup>\u00ae<\/jats:sup>\n                      graft and the renal vein was implanted. The patient's postoperative period was uneventful.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>DISCUSSION:<\/jats:title>\n                    <jats:p>Germ cell tumors of retroperitoneum are usually seen in children, but there are also some reports of adult cases in the literature. Adult cases are especially seen in females. Imaging studies are paramount for diagnosis, preoperative strategy and safe surgical excision. CT scans and MRIs can identify various components of these tumors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>Even though primary retroperitoneal teratomas are quite rare in adults. Preoperative radiology imaging and strategy is critical for performing a safe surgery. The gold standard treatment strategy for this neoplasm is the surgical resection.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2012.08.017","type":"journal-article","created":{"date-parts":[[2012,9,28]],"date-time":"2012-09-28T17:46:03Z","timestamp":1348854363000},"page":"30-32","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":8,"title":["Curative surgery for locally advanced retroperitoneal mature teratoma in an adult.
