Summary
Sonography is effective for detecting intrapancreatic metastases, often revealing smaller lesions missed by CT scans. This imaging modality aids in diagnosing pancreatic tumors in patients with known malignancies.
Area of Science:
- Radiology
- Oncology
- Gastroenterology
Context:
- Intrapancreatic metastases from solid tumors are uncommon but clinically significant.
- Accurate imaging is crucial for diagnosis and management.
Purpose:
- To compare sonographic and CT findings in patients with intrapancreatic metastases.
- To evaluate the diagnostic performance of each modality for detecting these lesions.
Summary:
- Sonography identified hypoechoic intrapancreatic lesions in 19 patients.
- CT detected hypodense lesions or contour bulging in 15 patients.
- Sonography detected smaller metastases (<2 cm) missed by CT in 5 patients.
Impact:
- Sonography is a sensitive tool for detecting intrapancreatic metastases, especially smaller ones.
- Findings suggest sonography complements CT in evaluating patients with known malignancies and suspected pancreatic lesions.
