Zusammenfassung
GRUNDLAGEN: Gutartige retroperitoneale Zysten sind selten, jene mit flüssigem Inhalt, der CA-125 und CA 19-9 enthält, noch seltener. METHODIK: Wir berichten über eine 38-jährige Frau mit einer Zyste zwischen Colon ascendens und rechter Niere. Der Zysteninhalt zeigte erhöhte Werte für CA 125 (2.798 U/ml), CA 19-9 (49 U/ml) und Amylase (1.283 U/ml). ERGEBNISSE: Die Zyste wurde reseziert, es fand sich eine gutartige retroperitoneale Zyste. SCHLUSSFOLGERUNGEN: Unser Fall ist der 2. einer retroperitonealen Zyste mit hohen Tumormarker-Konzentrationen und Amylase in der englischsprachigen Literatur.
Summary
BACKGROUND: Benign retroperitoneal cystic masses are uncommon clinical entities, and those with high cyst fluid levels of cancer antigen 125 and carbohydrate antigen 19-9 are extremely rare. METHODS: A 38-year-old woman was admitted to our hospital due to a right abdominal cystic mass. Computed tomography revealed a unilocular cystic mass without nodule between the ascending colon and the right kidney. The cyst fluid levels of cancer antigen 125, carbohydrate antigen 19-9, and amylase were elevated to 2,798 U/ml, 49 U/ml, and 1,283 IU/l, respectively. RESULTS: The patient underwent excision of the retroperitoneal cystic mass, and histologic findings confirmed the diagnosis of benign retroperitoneal cyst. CONCLUSIONS: To the best of our knowledge, our patient is the second case of a benign retroperitoneal cyst containing fluid with a high concentration of cancer antigen 125, carbohydrate antigen 19-9, and amylase in the English literature.
