case_images: Contrast-enhanced plain CT showed the mass in close contact with the surrounding blood vessels (A, B). After 2 months of targeted immunotherapy, the tumor was slightly reduced, and the relationship with the surrounding blood vessels was clearer (C, D). After conservative treatment for more than 1 year, the mass was significantly reduced and a ring of high-density shadow appeared around it, which was considered to form a calcification package (E-H). The size of the mass remained the same, whereas the density of the annular calcification layer increased (I, J).

case_images: Contrast-enhanced CT of the upper abdomen revealed a mass in the pancreatic neck with dilatation of the pancreatic duct, suggestive of a tumor ( Figure 1 ).
case_images: Changes in CA125 (A) (reference range: 0-35) and CEA (B) (reference range: 0-10) levels in the patient before and after treatment. These tumor markers showed a brief elevation in the initial treatment stage, followed by a decrease below the baseline level. Lymphocyte percentage (LY%) (C) returned to normal after three cycles of targeted immunotherapy (reference range: 20.00-50.00 %), and peripheral monocyte percentage (MO%) (D) returned to normal after the first cycle of targeted immunotherapy (reference range: 3.00-10.00 %).

case_images: The patient's lymphocyte percentage (LY%) was 15.9% (reference range: 20-50%), and the peripheral monocyte percentage (MO%) was 6.1% (reference range: 3-10%) ( Figure 2 ).
