Current Case:

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.

The initial plan was to biopsy the left para-aortic node using a posterior transpsoas approach.

However, since 10 weeks had elapsed, a repeat CT scan was done, which showed marked increase in the size of one of the enlarged pre-aortocaval nodes.

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.
