title: A case of retroperitoneal pseudomyxoma.
abstract: We experienced a rare case of pseudomyxoma that progressed into the retroperitoneum. This patient presented with complaints of polyuria and back pain. CT and MRI showed a retroperitoneal cystic tumor. Surgical and pathological findings confirmed mucinous cystadenoma of the appendix that reached the posterior space behind the right kidney through the retroperitoneum.
