Multislice CT reveals previously unseen mets in RCC
MSCT findings and histological feature correlations of pancreatic metastases from clear renal cell carcinoma.
Purpose
The growing use of MSCT in the follow-up of oncologic patients allows early detection of very small pancreatic lesions and particularly of secondary neoplasms.
Material and Methods
We present three cases of pancreatic metastases from clear renal carcinoma confirmed with 64-row MSCT and with histological confirmation of primary RCC and related metastases.
Results
In larger lesions, intravascular contrast administration reveals the differentiation between hypercellular periphery and internal hypodense portions. The hypercellular regions are less vacularized (Figures 1 and 2).
Smaller lesions, seen by more enhancement on arterial phase, were visible as a small spot of extraductal iodine hyperimpregnation and showed a persistence of iodine staining on later scans. Histologically, these demonstrate a prevalence of microvessels and hypercellularity with reduced interstitial anarchy (Figures 3, 4, 5).
Conclusion
It’s probable that the use of recent MSCT scanners, with their superior spatial and temporal resolution, reveals small pancreatic lesions that formerly were missed. In these patients subsequent surgical and medical treatment results in high survival, but makes radiological follow-up extremely important.

Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
