MSCT findings and histological feature correlations of pancreatic metastases from clear renal cell carcinoma.
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.
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.
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).
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.

Can AI Enhance CT Detection of Incidental Extrapulmonary Abnormalities and Prediction of Mortality?
September 18th 2024Emphasizing multi-structure segmentation and feature extraction from chest CT scans, an emerging AI model demonstrated an approximately 70 percent AUC for predicting significant incidental extrapulmonary findings as well as two-year and 10-year all-cause mortality.
Comparing Digital Breast Tomosynthesis to Digital Mammography: What a Long-Term Study Reveals
September 17th 2024In a study involving over 272,000 breast cancer screening exams, digital breast tomosynthesis (DBT) had a higher breast cancer detection rate and a lower rate of advanced cancer presentation at the time of diagnosis in comparison to digital mammography.
Can Radiomics Enhance Differentiation of Intracranial Aneurysms on Computed Tomography Angiography?
September 17th 2024Radiomics models offered a pooled AUC of 86 percent for differentiating between ruptured and unruptured intracranial aneurysms, according to a recently published meta-analysis.
