Case in brief
A woman with long-standing type 2 diabetes mellitus experienced worsening glycemic control due to an intraductal papillary mucinous neoplasm (IPMN). Laboratory tests indicated severe pancreatic exocrine insufficiency, and imaging revealed a ductal lesion consistent with IPMN. Endoscopic ultrasound and biopsy confirmed a main-duct IPMN, leading to a pancreaticoduodenectomy. Pathology showed low-grade disease without invasion, emphasizing the link between pancreatic disease and glucose metabolism.
What made this case unusual
The case illustrates how a precancerous pancreatic tumor can lead to pancreatogenic diabetes and malabsorption, highlighting the complex interplay between structural pancreatic disease and metabolic dysfunction.
Diagnostic / clinical pearl
Clinicians should consider the potential for worsening glycemic control in patients with type 2 diabetes who present with new gastrointestinal symptoms, as this may indicate underlying pancreatic pathology.
Why it matters
This case emphasizes the importance of early recognition of pancreatic conditions that can affect diabetes management and the need for tailored therapeutic approaches in patients with pancreatic insufficiency.
