 | Media file 1: Plain radiograph of the abdomen shows calcific opacities in the region of left lower renal pole. Note the reversed axis of the kidneys, which suggests horseshoe kidney. |
 | Media file 2: Intravenous urogram (IVU) shows an altered renal axis with medially directed lower renal poles, which suggests horseshoe kidney. Also note the dilated collecting system of the left kidney, resulting from a ureteropelvic junction obstruction; this is a frequently associated finding. |
 | Media file 3: Intravenous urogram (IVU) demonstrates horseshoe kidney. Note the malrotated collecting systems on both sides. The lower pole calyx of the right kidney lies medial to the ureter. |
 | Media file 4: Axial computed tomography (CT) scan obtained through the abdomen after the intravenous administration of contrast material. Fused kidneys are revealed, with a parenchymal isthmus at the lower poles. Note the malrotated collecting system of the left kidney, facing anterolaterally. |
 | Media file 5: Computed tomography (CT) scan of the abdomen obtained after the intravenous administration of contrast material. The isthmus of a horseshoe kidney, consisting of parenchymal tissue, is clearly demonstrated. Note the cortical continuity of the fused kidneys. |
 | Media file 6: Axial contrast-enhanced T1-weighted magnetic resonance image shows the isthmus of a horseshoe kidney; it consists of parenchymal tissue and lies anterior to the spine. |
 | Media file 7: Transverse ultrasonogram of the abdomen showing a soft-tissue hypoechoic mass (isthmus) that is anterior to the spine and aorta and that unites the lower renal poles. |
 | Media file 8: Transverse slightly oblique ultrasonogram of the right kidney, showing the lower pole of the right kidney; the pole crosses over the spine, anterior to the aorta and inferior vena cava. |
 | Media file 9: Posterior technetium-99m methylene diphosphonate nuclear medicine bone scan shows incidental findings that suggest horseshoe kidney. |
 | Media file 10: Angiogram shows incidental findings of a horseshoe kidney. The lower poles are connected by a fibrous isthmus. |
 | Media file 11: Transverse sonogram of the abdomen demonstrates a soft-tissue isthmus anterior to the spine. |
 | Media file 12: Intravenous urogram (IVU) of a male patient displays findings consistent with the presence of horseshoe kidney. |
 | Media file 13: Ultrasonogram of a pediatric patient displays a hypoechoic soft-tissue mass anterior to the spine. The finding is consistent with the presence of horseshoe kidney. |
