Recurrence of inflammatory pseudotumor in the distal bile duct: Lessons learned from a single case and reported cases

Figure 1 CT scan revealing a well delimited solid mass (arrow), without enlarged regional or para aortic lymph nodes and any evidence of invasion of other organs.

Figure 2 CT scan showing a clear relationship between tumor and inferior cava vein (arrow).

Figure 3 Serial magnetic resonance imaging of the abdomen (coronal plane) showing the tumor mass in the porta hepatis in close relation with the portal vein and biliary tract.

Figure 4 Dynamic classifications for autoimmune pancreatitis. A-E: Classification of the variable involvement of the hepatobiliopancreatic system which may be observed in patients with autoimmune pancreatitis. In yellow color is shown the affected zone. ^Ref References of the most relevant and reliable studies that identify this specific pattern of disease. F: Multisystemic organ involvement by inflammatory pseudotumor at the biliopancreatic region. In yellow color is shown the affected zone. ^Ref References of the most relevant and reliable studies that identify this specific pattern of disease.
