What are some clinical differential diagnoses for right sided abdominal pain?
Cholecystitis, appendicitis, ureteric colic, diverticulitis (more commonly left sided), omental infarction / epiploic appendagitis...
Are renal cell carcinomas usually painful? How do they classically present?
No, in general RCC are painless, and classically present with haematuria.
What is the likely T stage of this renal cell carcinoma?
If the apparent invasion into the fat immediately adjacent to the left diaphragmatic crus and splenic artery is real, then this is a T4 tumour.
The vermiform appendix is thickened and surrounded by extensive stranding in the surrounding fat. There is no abscess formation or free intra-abdominal air.
Additionally left upper pole renal mass is present consistent with a renal cell carcinoma. The fat plane between the left crus of the diaphragm and the splenic artery above the mass is lost, which is suspicious for local invasion.
