Abstract

Autoimmune pancreatitis (AIP), a rare form of chronic pancreatitis, is often misdiagnosed due to its overlap with other causes of pancreatic inflammation. We report an unusual case of an 18-year-old female who developed acute pancreatitis in the context of dengue fever. Persistent elevation of pancreatic enzymes and characteristic imaging led to further evaluation, confirming Type 1 AIP through elevated serum IgG4, weakly positive ANA, and histopathology. This case emphasizes the need for a comprehensive diagnostic approach to avoid delayed diagnosis and prevent irreversible organ damage.
