Fig. 1A. 37-year-old man with bilateral retroperitoneal leaks. Axial
fat-saturated turbo spin-echo T2-weighted MR image obtained after continuous
ambulatory peritoneal dialysis shows large bilateral fluid collections
(arrows) in perirenal space.

Fig. 1B. 37-year-old man with bilateral retroperitoneal leaks. Axial
T1-weighted fast low-angle shot MR image reveals residual
gadodiamide-dialysate mixture in peritoneal cavity (open arrow). Note
leakage of hyperintense fluid into perirenal space (solid
arrows).

Fig. 2A. 29-year-old man with recurrent right-sided pleural effusions caused
by diaphragmatic leakage after continuous ambulatory peritoneal dialysis.
Axial T1-weighted fast low-angle shot MR image shows hyperintense
gadodiamide-spiked dialysate in peritoneal cavity (short solid arrow)
and in right pleural cavity (open arrow). Note small leak in right
hemidiaphragm (long solid arrow).

Fig. 2B. 29-year-old man with recurrent right-sided pleural effusions caused
by diaphragmatic leakage after continuous ambulatory peritoneal dialysis.
Intraoperative view onto right hemidiaphragm confirms small mushroom-shaped
defect (arrows).

Fig. 2C. 29-year-old man with recurrent right-sided pleural effusions caused
by diaphragmatic leakage after continuous ambulatory peritoneal dialysis.
Intraoperative view shows that patch was sutured over defect. Arrow points to
patch.

Fig. 3A. 42-year-old woman with large leak in right hemidiaphragm. Axial
T1-weighted fast low-angle shot MR image obtained before continuous ambulatory
peritoneal dialysis shows large amount of peritoneal fluid (thick solid
arrow) and opacified right-sided pleural effusion (open arrow).
Note large discontinuity of right hemidiaphragm (small solid
arrow).

Fig. 3B. 42-year-old woman with large leak in right hemidiaphragm. Coronal
fat-saturated T1-weighted fast low-angle shot MR image shows buckling of
hemidiaphragm suggestive of discontinuity (arrow).

Fig. 5. 46-year-old woman with abdominal wall leak after kidney
transplantation failure. Axial T1-weighted fast low-angle shot MR image shows
left-sided kidney transplant. Note large ipsilateral fluid collection
(arrow).

low-angle shot MR image reveals inguinal hernia filled with gadolinium-spiked
fluid (arrow).
