The transdiscal approach has been described for nerve block and neurolysis of the hypogastric and celiac plexuses for chronic pain relief; however reports utilizing transdiscal approach for biopsy of aortocaval lymph nodes or other retroperitoneal masses are scarce. Traditional posterior paravertebral, lateral, or anterior approaches are often not technically feasible for core biopsy of aortocaval lesions due overlying bowel, organs, or vessels. In aortocaval or other retroperitoneal lesions inaccessible by traditional techniques the transdiscal method is invaluable in providing a linear approach that avoids the major vessels, organs, and bowel and allows for core biopsy. This case report demonstrates the use of transdiscal approach for core biopsy of aortocaval lesions otherwise inaccessible by traditional approaches
