Abstract

Retroperitoneal tumors pose diagnostic and treatment challenges due to their deep anatomical location and often minimal early symptoms. This case study details a laparoscopic approach for the removal of a benign retroperitoneal cyst involving diaphragm resection and repair. The patient, who presented with chronic right hypochondrial pain, was initially diagnosed with gallstone disease and based on imaging studies which proposed it as a parasitic cyst in the right liver lobe. But intraoperatively, a retroperitoneal tumor-like mass approximately 5 cm in diameter was found on the posterolateral wall, connected to the right dome of the diaphragm. Using a laparoscopic approach, the mass was excised within healthy tissue margins, followed by resection and plasty of the diaphragm. Histological analysis confirmed the benign nature of the tumor, likely a teratoma with calcified and necrotic areas. The patient’s postoperative recovery was smooth, with no complications, and they were discharged in satisfactory condition for further outpatient care.
