case_images: Abdominal CT scan upon admission for this case. (A) Acute pancreatitis is characterized by pancreatic swelling, which is more pronounced in the tail of the organ. Enhanced local density is slightly reduced, while widespread exudative fluid accumulates around the abdominal aorta, splenic artery, and anterior renal fascia. The fascia in front of the left kidney is thickened, and the interstitial spaces of abdominal fat are unclear. (B) The density of the spleen was significantly reduced, and enhancement was markedly decreased, suggesting splenic infarction. The interstitial spaces of abdominal fat were unclear.

case_images: The specific performance might be peripancreatic fluid collection, thickening of the peritoneum and omentum, homogeneous decrease in splenic density, and homogeneous increase in gallbladder density (Figure 1). Moreover, Extensive fluid accumulation was observed surrounding the abdominal aorta, splenic artery, and anterior renal fascia, with blurred fat planes in the abdominal cavity (Figure 1).
case_images: Chest CT scan upon admission for this case. The inflammation and partial consolidation in the bilateral lower lobes of the lungs, along with bilateral pleural effusion.

case_images: The chest CT scan indicated inflammation in the bilateral lower lobes of the lungs, minimal pleural effusion, and atelectasis in the lower lobes of both lungs (Figure 2).
case_images: Abdominal CT scan at the time of discharge for this case. (A) The pancreas demonstrates an enlarged morphology with heterogeneous internal density. There are patchy areas of slightly lower density with indistinct borders. A local drainage tube has been implanted. (B) The spleen appears normal, with no apparent abnormalities in density.

case_images: The results of the follow-up abdominal CT scan are consistent with the ultrasound findings (Figure 3).
case_images: Chest CT scan at the time of discharge for this case. Bilateral pulmonary inflammation shows significant absorption, with minimal pleural effusion observed bilaterally.

case_images: CT reveals improved pneumonia bilaterally, with minimal pleural effusion in both lungs (Figure 4). Considering the significant improvement in the patient's condition, the patient was discharged on the twenty-fourth day of admission.
