• Based on the percutaneous biopsy literature, ML-based CT texture analysis has a comparable predictive performance with percutaneous biopsy. • Highest predictive performance was obtained with use of the SVM. • SVM correctly classified 85.1% of cc-RCCs in terms of nuclear grade, with an AUC of 0.860.

Although relatively uncommon, appendiceal diverticulitis should be included in the differential diagnosis of acute appendicitis. It differs from typical acute appendicitis by the presence of an inflamed diverticulum, seen on CT. These patients are also more likely to have peri-appendiceal extra-luminal loculated fluid, peri-appendiceal fat stranding, and a larger diameter of the appendix. The latter finding is likely due to the increased intraluminal pressure.
