A 71-years old treated in the past for T-cell lymphoma came with new active nodes on a PET/CT with splenic involvement. The biopsy for some reason for deferred for 10 weeks.

A decision was made to biopsy this node using an anterior approach in the supine position.
The video discusses the case, the approach with a detailed discussion of the various approaches for retroperitoneal lesion biopsies with a new diagram.
