We report a case of late type III B endoleak from a fabric tear in the main body of a Zenith bifurcated stent-graft approximately 19 months after implantation. A follow-up computed tomography (CT) scan showed gradual growth in the size of the aneurysm, but no apparent endoleak was recognized. However, the CT scan had demonstrated a mosaic pattern in the aneurysm sac, which could indicate an endoleak from a fabric tear. The defect was repaired by implantation of body extensions, but the patient died 5 h after the procedure.
