A Retroperitoneal Mass Encasing the Renal Hilum Presenting as a Parapelvic Tumor: A Case Report with Laparoscopic Resection Approach

We present a case with the hilar lesion of the left kidney that was managed with laparoscopic resection. The laparoscopy revealed that the mass completely enclosed the left renal hilum, but the mass was excised without any complication. The final pathologic report revealed a benign mesenteric cyst. Although most of the retroperitoneal mass had a malignant etiology, in cystic lesions in the renal hilar area, the benign mesenteric cyst may keep in mind the differential diagnosis of a mass in this anatomic region.Case Rep Oncol 2022;15:695 –699
