Summary
Computed tomography (CT) findings in pancreatic tuberculosis (PT) differ between HIV-seronegative and AIDS patients. Non-AIDS patients typically present with focal pancreatic masses, while AIDS patients show varied CT presentations, including nodules or diffuse enlargement.
Area of Science:
- Radiology
- Infectious Diseases
- Gastroenterology
Background:
- Pancreatic tuberculosis (PT) is a rare form of extrapulmonary tuberculosis.
- Accurate diagnosis of PT can be challenging due to its nonspecific presentation.
Purpose of the Study:
- To delineate the computed tomography (CT) imaging characteristics of pancreatic tuberculosis.
- To differentiate CT findings in patients with and without AIDS.
Main Methods:
- Retrospective review of CT scans from six patients diagnosed with PT.
- Analysis of imaging features, including lesion morphology, attenuation, and associated findings.
Main Results:
- Focal pancreatic masses were observed in four patients (all HIV-negative).
- Findings in AIDS patients included focal masses, small nodules, or diffuse pancreatic enlargement.
- Peripancreatic/periportal adenopathy with rim enhancement was noted in three cases.
Conclusions:
- CT findings in PT vary based on HIV status.
- Nonspecific focal masses are common in HIV-negative individuals.
- AIDS patients exhibit a broader spectrum of CT findings, with adenopathy suggesting PT.
