Summary
Pancreatic lipomas are rare, fatty tumors incidentally found via imaging. These silent lesions exhibit specific computed tomography (CT) findings and typically do not require further diagnostic evaluation.
Area of Science:
- Gastroenterology
- Radiology
- Oncology
Background:
- Fatty tumors of the pancreas, or pancreatic lipomas, are infrequently documented.
- Advancements in radiologic imaging techniques have led to an increased diagnosis of these tumors.
Purpose of the Study:
- To review the computed tomography (CT) imaging findings of pancreatic lipomas.
- To establish characteristic radiologic features for diagnosing pancreatic lipomas.
Main Methods:
- Retrospective review of four patients diagnosed with pancreatic lipomas via CT between June 2006 and June 2012.
- Analysis of imaging findings, including lesion characteristics, size, density (Hounsfield units), and location.
Main Results:
- All patients presented with a single, well-bordered, nodular fatty lesion with a thin, homogeneous capsule.
- Lesion size ranged from 7 to 12 mm (mean 8.75 mm), with a mean density of -76 HU.
- Lipomas were located in the pancreatic tail, body, and neck; no associated pancreatobiliary pathology was observed.
Conclusions:
- Pancreatic lipomas are typically asymptomatic and incidentally discovered.
- Specific CT findings allow for confident diagnosis, often obviating the need for further imaging or histopathologic evaluation.
