There is irregular diffuse thickening observed in the body and fundus of the gallbladder, measuring approximately 11-14 mm. This thickening shows restricted diffusion and heterogeneous enhancement, without any evidence of fatty infiltration in this region. Additionally, intramural cavities are noted in the fundus of the gallbladder, along with a gallstone measuring about 7 x 9 mm.
A retroperitoneal mass is located in the pancreatic head, extending into the hepatic hilum. This mass surrounds various vascular structures, including the inferior vena cava, abdominal aorta, celiac trunk, and right and left renal arteries. It shows an indistinct margin, restricted diffusion, and enhancement. Furthermore, the lesion compresses and narrows the common bile duct, with the narrowest diameter measuring approximately 3 mm.
Additionally, there is a right pleural effusion and a nodal lesion in the left lung.
Duodenal diverticulum is noted.
