Case Discussion

A beautiful example of the multi-factorial role played by a modern clinical imaging department, in performing both non-invasive and invasive diagnostic procedures and assisting in treatment.

This patients hydronephrosis and so renal impairment was secondary to an abscess in the right para-aortic space, diagnosed with a CT guided aspiration and temporized with a percutaneous nephrostomy tube insertion.
