Summary
Computed tomography (CT) is a key tool for diagnosing pancreatic abscesses and infected pseudocysts. Pancreatic gas collections on CT are the only definitive sign of infection, guiding further diagnostic steps.
Area of Science:
- Radiology
- Gastroenterology
- Surgical Diagnostics
Background:
- Pancreatic abscesses and infected pseudocysts are serious complications requiring accurate diagnosis.
- Computed tomography (CT) is frequently employed for evaluating pancreatic pathologies.
Purpose of the Study:
- To evaluate the utility of CT in diagnosing pancreatic abscess and infected pseudocyst.
- To identify definitive CT features indicative of pancreatic infection.
Main Methods:
- Computed tomography (CT) was utilized as the primary diagnostic modality.
- Reviewed 10 cases of pancreatic abscess and seven of infected pseudocyst.
Main Results:
- Pancreatic gas collections were the sole definitive indicator of infection, present in 29% of cases.
- Poorly defined peripancreatic fluid collections or mottled mass density were common but non-specific findings.
- CT criteria alone could not reliably differentiate infected from non-infected pseudocysts or fluid collections.
Conclusions:
- Diagnostic percutaneous needle aspiration is recommended for pancreatic pseudocysts or fluid collections with persistent fever or leukocytosis.
- CT remains valuable for preoperative assessment of multiple or recurrent pancreatic abscesses.
