UNASSIGNED: Immunoglobulin G4 (IgG4)-related disease is a rare @entity262 . A 67-year-old male presented at our institution with mild @entity490 and @entity1087 for 20 d. Laboratory results revealed high levels of IgG4 (15.4 g/L, range: 0.08-1.4 g/L). Computed tomography (CT) showed significant enlargement of the entire pancreas and a capsule-like low-density rim surrounding the whole pancreas. Positron emission tomography/CT revealed increased uneven metabolism of the entire pancreas. Both magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography showed @entity850 of the distal common bile duct and proximal main pancreatic duct, and dilation of the proximal common bile duct and extra- and intra-hepatic bile ducts. He was diagnosed with IgG4-related autoimmune @entity788 . The @entity1 was treated with @entity229 for 14 mo. The @entity1 responded well to @entity229 but upon cessation of the corticosteroid developed enlargement of the submandibular gland. The patient's serum IgG4 was elevated at 23.9 g/L. It is important to maintain treatment, so the @entity1 was again treated with @entity229 and had a good response. Follow-up of IgG4-related disease is thus necessary.
