Recurrent retroperitoneal tumor

Due to the hidden location of the retroperitoneal tumor, early diagnosis is difficult, and most of them are in the middle and advanced stages when found. One-third of the cases are misdiagnosed and received incorrect treatment. Therefore, whether it is a malignant or benign tumor, it is very easy to relapse after surgical resection. Finding small recurrences in time can gain time and initiative for reoperation.
