Figure 1
Contrast‑enhanced axial CT images in the venous phase. (a) Hepatomegaly with prominent intrahepatic bile ducts (arrows). (b) Thickened and enhancing bladder wall with perivesical fat stranding, consistent with inflammatory cystitis. Symmetric mural thickening of the mid‑portion causes luminal narrowing, producing an ‘hourglass’ configuration.
Figure 2
Contrast‑enhanced axial (a, b) and coronal (c, d) CT images in the venous phase. Both kidneys appear bulky with delayed nephrograms and reduced corticomedullary differentiation. The walls of the renal pelvis and ureters are thickened and demonstrate marked contrast enhancement (yellow arrows). The bladder appears small and compressed with a markedly hypertrophic wall, indicating reduced capacity (blue arrow).
Figure 3
Axial (a, b, d) and coronal (c) T2‑weighted HASTE fat‑suppressed MR images showing hepatomegaly with prominent intrahepatic bile ducts and bilaterally enlarged, bulky kidneys.
Figure 4
Axial diffusion‑weighted (DWI) image (left) and corresponding apparent diffusion coefficient (ADC) map (right) showing restricted diffusion within the renal parenchyma, consistent with interstitial nephropathy.
Figure 5
Axial T1‑weighted MR images acquired before and during the arterial post‑contrast phase demonstrate mural enhancement of the intrahepatic bile duct walls (a) and ureteral walls (b), consistent with inflammatory cholangitis and ureteritis, respectively. Enlarged views in the blue boxes highlight the areas of mural enhancement. Yellow arrows indicate the enhancing walls.
