Acute pancreatitis secondary to small-cell lung cancer metastasis: A case report and literature review

Figure 1 Summary of the analytical evolution during hospitalization for acute pancreatitis and follow-up after four cycles of chemotherapy. AP: Acute pancreatitis; ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; CRP: C-reactive protein; GGT: Gamma-glutamyl transferase; ALP: Alkaline phosphatase; NSE: Neuron-specific enolase; ProGRP: Pro-gastrin-releasing peptide.

Figure 2 Ultrasound images showing some of the pancreatic metastases (arrows). The largest one, measuring 21.6 mm, is highlighted. A: Metastatic lesion was identified in the distal pancreatic body; B: Additional lesions were noted in the pancreatic tail region; C: The main lesion, located in the pancreatic body prior to measurement; D: Measurement of the largest lesion (21.6 mm).

Figure 3 Images from computed tomography performed at the diagnosis of small cell lung cancer. A: Coronal section, showing the hypodense lesion classified as nonspecific (arrow); B: Axial section displaying the same lesion in this plane (arrow).

Figure 4 Follow-up computed tomography. A cystic lesion at the level of the pancreatic head-uncinate process compatible with a pancreatic pseudocyst is observed. A: Axial view showing a cystic lesion; B: Coronal view showing a cystic lesion.

Figure 5 Timeline summarizing the most important events in clinical progression. CT: Computed tomography.
